CHAPTER ONE
1.0 INTRODUCTION
The student industrial work experience scheme (siwes) is an approved skill training scheme which
forms part of the minimum academic standards in various degree scheme for all Nigerian universities to
acquire skills and experience in their various course of study.
Student Industrial Work Experience Scheme was established by the Industrial training Fund (ITF) in
1973 with the aim of bridging the gap between the skills which the labour market required with that of
those acquired by the graduate students. Since its introduction by the ITF in 1973 the Scheme has gone
through series of reforms. its management, for instance, has changed hands from the ITF to the various
regulatory AGENCIES SUCH AS National Universities Commission (NUC) National board for
Technical Education (NBTE) and National Commission for college of Education (NCCE) and now
back to the ITF again. These are the major stakeholders in (SIWES).
Consequently, SIWES Programmed was introduced into the curriculum of tertiary institutions in the
country as far back as 1974 with 748 students from 11 institutions of higher learning.
However, the scheme has over the years contributed immensely to the persona l development and
motivation of students to be able to understand the important connection between the taught and learnt
content of their academic programmed and what knowledge and skill will be expected of them on
professional practice after graduation. In recognition of the short courses and weakness in the formation
of Set graduates, particularly with respect o acquisition of relevant production skills, the industrial
training fund established the students Industrial Work Experience Scheme (SIWES) in 1973. The
Scheme was designed to expose students to the industrial environment and enable them develop
occupational experiences so that they can readily contribute their quota to national economic and
technological development after graduation. Consequently, SIWES is a planned and structured
programmed based on stated and specific career objectives, which are geared toward developing the
occupational competencies of participants.

1.1 OBJECTIVE OF THE STUDENTS INDUSTRIAL WORK EXPERIENCE
PROGRAMME
The Industrial training funds policy document no. 1 of 1973, which established SIWES outline the
objectives of the scheme. The objectives are to:
1. Provide an avenue for students in institution of higher learning to acquire industrial skills and
experience during their course of study.
2. Prepare students for industrial work situation that they are likely to meet after graduation.
3. Expose students to work methods and techniques in handling equipment and machinery that may not
be available in their institutions.
.4. Make the transition from school to the world of work carrier and enhances students contacts for later
job placements.
5. Provide students with the opportunities to apply their educational knowledge in real work situations,
thereby bridging the gap between theory and practical.
1.3 BENEFITS OF INDUSTRIALTRAINING TO STUDENTS
The industrial attachment seeks to offer students a practical translation of the theory they have been
taught. It has also got individual benefit of linking the University to the industries, hence brightening
the employment chances of the students in the University.
Through this attachment, I have generated a good inter personal relationship through my interaction
with my supervisors and colleagues. It has also improved my working skills either under pressure with
or without supervision.

2.4 DEPARTMENTS/ UNITS IN THE ESTABLISHMENT AND THEIR FUNCTIONS
There are basically five departments/Units in Bioraj Pharmaceutical Limited.
There department and their functions are briefly outlined below.
2.4.1 Administration Department: The department consists of accounting section, Auditing,
Sales and marketing.
i) Account section is concerned with financial(money) stuff of the company
ii) Auditing examines the company financial records to check that they are correct
iii) Sales and Marketing deals with how the products produced gets to market.
2.4.2 Raw Materials (Store) Department: This is the department where all pharmaceutical
products and ingredients such as chemicals, starch, paracetamol etc. Are kept safe for used at a
standard condition. Some instruments in the department include; Weighing balance
Thermometer, Relative Humidity meter. The department is partitioned into various rooms such
as;
(1) The quarantine room: This is a sub-section in the raw material department
where all incoming and supplied materials are first kept. Raw materials in this
section are yet to be tested or approved for use by the chemical analyst.
(2) Raw material loading qbay: This is a sub-section in the raw materials
department where raw materials that have been tested and approved for use are
kept. Such raw material has undergone both chemical and microbial analysis and
its potency has been confirmed.

15. 15
(3) Cold room: In this room, approved raw materials that are temperature specific
are kept at their specified temperatures such as vitamins e.g. vitamin Ferric
ammonium citrate, Menthol crystal. The specific temperature should always be
kept below 25 oC.
(4) Poisonous Room: this is the room where all poisonous raw materials are kept in
order to avoid misinterpretation and to implement effective sorting. Example of
chemicals in the room are caffeine, codeine etc.
(5) Reject room: This is a room where raw materials that has failed the required tests
are kept. Raw materials in this room are known as ‘reject’ as they are not suitable
for use. Most commonly find include paracetamol because of present of 4-amino
phenol which is an impurity which blackness of paracetamol.
2.4.3 Production Department
This department is mostly known as active department of the company because it is responsible
for ensuring quality is achieved in each production stage through the activities of in-process
checks. Basically, they are responsible for the production and packaging of drugs.
It is divided into two sections (Solids and Syrup) and each section caries out different duties,
they are.
i) Dispensary Section/Weighing room: : This section is the gateway for all the raw
materials used in the production department, they normally carry out weighing and
dispensing of all raw materials with the aid of Electronic weighing balances as
specified in the batch operation.
ii) Granulation Section (Solids): This section is where granules are being prepared by
Mixing, Milling, Drying, Sieving, Crushing and Blending of the dispensed raw
materials according to the procedure set by the quality control to produce the required
product. The machines used in granulation section includes Rapid Mixer granulation,
Multi-mill machine, Fluidized bed dryer, Vibro-Sifter, Comminuting mill and
Octagonal blender.

16. 16
iii) Compression Section: Compression is the process by which granules are turned into
solids form which can be circular called “tablets” or oblong called “caplets”. This is
done with the aid of a compressing machine that consists of a die and punch.
iv) Encapsulating section: This is where empty gelatine is filled with drug powder with
the aid of capsulation machine.
v) Coasting Section: This is where some tablets that cannot be taken directly are being
coated with coating machine some of these drugs include; ferrous sulphate, and
Ibuprofen.
vi) Blistering section: This is where compressed, coated and capsulated drugs are being
blistered. I.e. putting them into polyvinyl chloride (PVC) and aluminium foil with the
aid of blistering machine.
vii) Compounding Unit (Syrup section): This is the unit where appropriate ingredients
were being combined with aid of various tools to produced syrup drugs. Some of the
equipment presents in this unit include; Syrup mixing tank, UV water sterilizer, Filter
chamber, and filter press, Colloidal milling machine, Treated water tank and
compound tank.
viii) Filling Section: In this Section syrup produced are filled in the bottle, capped and
sealed. The 1st assignment of quality assurance is to make sure the environment where
production is to be take place is very clean and tidy. Distill water are been used for
the production process. The bottles are checked also, if it has crack or broken and
after filling the bottle with the product, check whether there is no particle inside. The
cap must be checked whether is sealed properly or not, also check the cap after
sealing whether it’s leaking or not. The label and leaflet must be applied properly.
ix) Packaging Section: This is where the blistered drugs are taken to, for packaging into
packets and also shrink wrapped using shrink wrapping machine.
x) Finished Product Store: Here approved finished products are kept before it will be
conveyed to the market.

17. 17
2.4.6 Quality Control Department
This department is otherwise known as the heart of the industry because it ensures the quality of
materials used and the finished product sold out to consumers for their consumption they are
mostly concerned with sample analysis, specifications, organization, and documentation to
ensure that the finished product and raw materials are of standard. The quality control has the
power and jurisdiction to approve or reject any component, after adequate laboratory procedures.
The quality control department is divided into Five Units, they are;
i) Chemistry Laboratory: This section/unit caries out series of test on different
products, they test for raw materials, finished drugs, running of assay of different
drugs samples, dissolution test etc. They also carries out the in-process controls such
as loss on Dryness test of granules, friability test, Disintegration test, Weight
Variation, leak test on blistered drugs etc. This role is very vital for the effective
functioning of the company in the area of quality and standardization.
ii) Microbiology Laboratory: This section caries out microbial control of production
Environment, Microbial analysis of raw materials, finished products and water. They
are also in-charge of treating, transferring and deionization of production water and
distillation of water used in laboratory analysis.
iii) In-Process unit: This is a sub-section of chemical laboratories where
production/product in-progress is monitored. Various tests such as pH, L.O.D,
running weight etc are carried out intermittently to ensure uniformity.
iv) Retention sample room: This is a section in the quality control department where
samples of each batch of products produced are kept for future purposes. This is done
to monitor the stability and the half-life of the drugs and in case of any complaints
about the product by customers so as to enable tracing the product batch and run full
analysis on it.
v) Instrumentation room: A separate instrument room, so – called control room, is
preferred, otherwise serious corrosion may spoil the costly instrument, electric supply
to the instruments should be controlled by suitable voltage stabilizer, while selecting

18. 18
major pieces of instrument, it should be ensured that facilities for maintenance are
available.
2.5. QUALITY ASSURANCE AND CONTROL IN PHARMACEUTICAL UNIT
The term quality assurance and control are often used to refer to ways of ensuring the quality of
a service or products. For each analytical procedure, quality assurance and control is extremely
important.
Quality assurance is process-oriented and it focuses on defect prevention while quality control
is product-oriented and focuses on defect identification. However, the objectives of a quality
assurance and control programme include:
 To document the procedures and methods of sample collections, preparations and
analysis.
 To provide assurance as to reliability of analysis using replicate samples and cross
laboratory checks.
 To provide assurance as to the accuracy from using recognised reference standards.
 To provide a chain of custody of samples.
 To provide assurance as to the precision and accuracy from the duplicate samples.
Both the quality assurance and control are after quality products and they function to see that
the products being produced are of high quality and standards by performing both chemical and
microbial tests to attest the potency of the products.
2.6. TRAINING/ORIENTATION IN BIORAJ PHARMACEUTICAL LIMITED,
Orientation is a routine done to any new intake of the company while training is done every half
year. My first day in Bioraj Pharmaceutical Industry, I was trained/ oriented by the chemical
analyst. And the GMP manager gave me the rules and regulations of the company. Thereafter,
she took me round the company and introduced me to some of the staff present on the day of
my resumption, both senior and Junior staff, even to my fellow I.T Student that have started
before me. She also took me to different suites/sections in the production department as well as
quality control department. After which I was posted to start in chemistry laboratory section of
quality control.

2.7.0 GOOD MANUFACTURING PRACTICES OF THE COMPANY
Good Manufacturing Practice (GMP) is that part of quality assurance which ensures that
products are consistently produced and controlled to the quality standard appropriate for their
intended use and as required by the marketing authorization. GMP aims primarily at
diminishing the risk inherent in any pharmaceutical production. Such risks include: cross
contamination and mix-up caused by for example, false labels being put on container.
This can be analyzed in three forms:
1. Dress Code/ Personnel Hygiene.
 Washing of hands and face before entering the production area.
 Clothing yourself with the overall to ensure that the dust probably in your street clothe
does not affect the product.
 The head is covered to ensure that hair does not enter thee product.
 Bathing and use of roll on, no hard smelling perfume.
 Use of Ornaments is not allowed.
 No edible thing should be taken into production area.
2. Product handling
 Products are not to be touched with bare hand.
 A product is handled at a time.
 The product must be put in keg
 Kegs are to be covered to avoid drug reactions.
 Before any keg is used, old labels must be removed and a new one placed.
 If at the course of operation the machine develops fault, protect the product by covering
before inviting the engineering team.

20. 20
3. Operational System
 An operator is meant to wear a good foot wear to avoid electric shock.
 A machine should be test run for some minutes before starting the process
 Check the parts to ensure they are functioning properly.
 Ensure proper alignment of the machine pulley and fan belt
 Ensure that your overall does not come in contact with any fast moving part of the
machine to avoid accident.
 Lubricate your machines daily before use to avoid wear and tear.

3.0 ACTUAL WORKDONE IN THE QUALITY CONTROL LABORATORY
CHEMICAL LABORATORY
All Pharmaceutical units need a Chemical Laboratory for Evalution of Raw material and
Finished products. A Chemical laboratory can undertake majority of the tests for Raw material
test like Solubility, Identifications reaction, Assay, Melting range, Moisture content, pH e.t.c
also Analysis of Water, Finished product both (Human and Animal) and Reagent preparation.
These products are analyzed to know if they are safe for human use or animal consumption. The
kinds of test(s) to be carried out on these products depend on the type of product to be analyzed.
The drugs can either be in tablets, capsules, syrup and suspension.
The following are the tests carried out on sample materials and Drugs:
1. Identifications test ( Qualitative analysis)
2. Assay analysis (Quantitative analysis)
3. Dissolution test Analysis
4. Physiochemical test (Physical parameters)
In the Chemical laboratory, analysis are majorly base on three major aspect, Analysis on raw
materials and Analysis on intermediate, finished products and Analysis on water
3.1 IDENTIFICATION TESTS ON RAW MATERIALS
These tests are carried out on samples to know whether the compounds used in manufacturing
the products as claimed by the manufacturers are present or not and also to know if the product
contains any harmful/impurities compound.
Analysis of Raw Materials

3.3.0 FINISHED PRODUCTS ANALYSIS (ASSAY).
Assay of finished product is an investigative procedure in the laboratory analysis for
quantitatively measuring the presence or amount of a target entity. The measured entity is
generally called the analyst (Wikipedia).
After the identification test is carried out on the drug sample, the said drug must pass the
ASSAY test in addition to the physical parameter test before the issuance of the drug. The aim
of this analysis is to quantify the amount of the active pharmaceutical ingredient present in the
drug sample. The method of analysis used by the analyst in the analyzing these drugs are
usually reviewed from the Standard Operating Procedure (S.O.P). The S.O.P is gotten from
either U.S.P or B.P which are standard compendia for the preparation and analysis of drugs. The
acceptable limit for Active ingredient that must be present in the drug sample is between 90%
and 110%.
3.3.1 PROCEDURE FOR FINISHED PRODUCT ANALYSIS (ASSAY)
 Carry out away on the drug sample in order to obtain the average weight of the drug (for
tablet, caplets, capsules) or determine the weight per ml of the drug sample if it is in liquid form
( suspension and syrups)
 Check the S.O.P for the method of analysis of the particular active ingredient being
worked on
 Prepare the solution of the drug sample following the method of analysis stated in the
S.O.P (which should contain the molar absorptive, or morality of reagent in titrimetric.)
 Find the weight taken by using the formula
Weight taken = Average weight (mg) × equivalent weight (mg)× 100
Claim weight (mg)
 Calculate the dilution factor using the formula
Dilution factor = a/100 × b/c × d/e.........
Where a= First volume make up
b = Second volume make up
c = No. of mistaken from first volume make up
d = No. of mistaken from second volume make up
e = Third volume make up

31. 31
 Shake or somicate the final solution if stated in the S.O.P.
 FOR INSTRUMENTAL METHOD;
 Proceed to the UV-Visible Spectrophotometer. Blank machine with the solvent
used to prepare the solution of the sample. Then take at least 3 absorbance of the
prepared solution of the drug sample.
 Then calculate the %Assay:
%Assay = Absorbance of sample × 100
Absorbance of standard
 FOR TITRIMETRIC METHOD:
 The method employed in volumetric analysis, in this method a solution from
graduated vessel (burette) is added to a known volume of a second solution until
chemical reaction between the two is just completed. This is shown by colour
change known as end point or in an indicator.
 Then calculate the % Assay;
%Assay = titra value × eq. wt × factor × 100

3.7.0 WATER TREATMENT AND WATER ANALYSIS
3.7.1 Water Treatment
Bioraj Pharmaceutical Industry gets their water supply from a borehole system. Before
the water is made use of, it goes through a water treatment plant. In this
treatment plant, the water passes through three stages of purification before usage.
a. Chemical Treatment:
The borehole water is first of all Channelled into a 1000litres over head tank
using pipes, in each pipe has a dosing value where a solution of 100g of soda
ash (Na2CO3) is added to the water for the removal of
non-carbonate hardness in water and to increase the pH of the water. After 5
mins a solution of 2g of chlorine is added to kill the micro-organisms present.
The reaction is allowed to take place for at least 30mins before opening the water
supply.
b. Filtration Process
The treated water is pumped into the portable water tank by passing it through the
sand filter chamber for the removal of sands and impurities that may be present
in the water. It moves to charcoal column which absorbs the taste of chlorine
and also colour, from where it moves into the micro filters for further
purification. From this point the water is made ready for consumption and use
in the factory.
c. Demineralization/Deionization
Deionised water is water that has had its mineral ions removed. From portable water
tanks, production water is passed through Deionization chamber containing
Cation resin, Anion resin and mixed bed, which provide ion exchange site for
replacement of the mineral salts in water. Deionization provides high purity
water that is generally similar to distilled water with zero conductivity.

Figure 3.7.1 Water Treatment Flow Chart
3.7.2 Water Analysis (Introduction)
Nowadays it is very important that continuous water samples are being taken and analyzed. For
example, drill water can often show high concentrations of chloride and iron. The basis of
evaluation for the water quality depends on what purpose is the water used for,.
Collection of Water Sample
Water sample running from a tap must be collected using a cleaned bottle, filled and shut
immediately but before collection, the tap must allowed to run for two to three minutes so as to
release the unwanted particles stored at the mouth of the tap and filled at least half of the
volume of the sample bottle which should be immediately taken to the laboratory for analysis..
In Bioraj Pharmaceutical Ltd, Two (2) types of water are of high importance for production.
These include the deionized water and the Raw Water, for both Production and General use
respectively. These waters follow a lot of processes to ascertain purity after which several test is
carried out by Q/A Analyst to determine its fitness.

48. 48
Water physical specification:
 Description: A Clear, Colourless, Odourless and tasteless liquid.
 It has a boiling point of 1000C
 Weight per ml (w/ml) = 0.996 - 1.0g/ml
The following are the tests carried out on water (both treated and raw) Physical test:
Appearance: Colourless, odourless liquid.
Hardness test
Chloride ion test
pH test
Conductivity test
I. Hardness Test: (Procedure)
100 ml of water was measured into a conical flask using measuring cylinder
2 ml of ammonium – ammonia buffer solution of pH 10.4 was added to the water.
Little Erichrome T black was added and it changes to pink colour.
Then it was titrated with EDTA, blue colour was observed which shows that all the ions (ca2+ &
Mg2+)
Then the titre value was recorded
Calculation of the total Hardness (T.H) is given
Titre value X 1000
Volume of water measured
II. Chloride Ion Test: (Procedure )
100 ml of water was measured into a conical flask
1 ml of potassium chromate was added and yellow colour was observed
Then it was titrated with silver nitrate (AgNO3)
A trace of faded brownish/orange colour was observed
It is being calculated as:
Titre value X 1000

49. 49
Volume of water measured
III. pH Test:
The pH test is used to determine the potential hydrogen concentration of the water sample.
There are basically two types of pH meter which are:
(i) Digital pH meter
(ii) Movable pH meter
pH = -log [H+]
IV. Acidity/Alkalinity: 10 ml of freshly boiled water and cooled water in a borosilicate glass
flask was added to 0.05 ml of methyl red solution. The resulting solution must not be in any
way Red. 10 ml of the same water sample was added to 0.1ml of bromothymol blue solution,
the resulting solution must not be in any way Blue.
V. Conductivity Test:
This can be carried out using conductivity meter. The calibration is done using Potassium
chloride. Potassium chloride is a buffer that is used to zero the conductivity meter or it can be
tare to zero on the meter. The main purpose we carry out this test is to know the presence of
ions present in the water sample. to zero the conductivity meter or it can be tare to zero on the
meter. The main purpose we carry out this test is to know the presence of ions present in the
water sample.

4.1.1 UV/VISIBLE-Spectrophotometer
UV-visible spectrophotometer is one of the most frequently employed equipment in
pharmaceutical analysis. It involves measuring the amount of ultraviolet or visible radiation
absorbed by a substance in solution. The law that governs the quantitative spectrophotometric
analysis is the Beer-Lambert law which states that the quantity of light absorbed by a
substance dissolved in a non absorbing solvent is directly proportional to the concentration of
the substance and the path length of the light through the solution. This law is accurate for dilute
solutions.
Fig.4.1: UV/visible-Spectrophotometer
Mode of operation:
 Power the machine by pressing the on/off button on it
 Set the appropriate wavelength
 Blank machine with the solvent used to prepare the solution of the sample.

CHAPTER FIVE
5.0 SUMMARY, CONCLUSION AND RECOMMENDATIONS
5.1 Summary
Having gone through the necessary training involved in student industrial work
experience scheme (SIWES) with the experience gained for six months; it is highly expedient for
me to summarize my report on the platform of what I engaged in during this period. More so, I
want to recall that during my industrial attachment at Bioraj Pharmaceutical Ltd, I was exposed
to series of tests and assays carried out on both raw materials and finished products which as
made me to appreciate the world of science and technology.
5.2 Conclusion
My Student Industrial Work Experience Scheme (SIWES) training with BIORAJ pharmaceutical
limited has provided an avenue for me to understand practical aspects of the theoretical
knowledge already acquired in some of the courses I have offered so far as an undergraduate of
industrial Chemistry department through the necessary verification tests carried out on water and
drugs to ensure that they are up to the expected standard for human use. SIWES has made me
acquainted to the work environment. I was also exposed to various laboratory
instruments/machines, equipment, professional work methods and ways to safe guard the work
environment in industries and various organizations. The Training has given me an opportunity
to understand some of the basic principles of chemistry which will further enhance my
knowledge of the course. This training also gave me the opportunity to interact, share knowledge
and ideas with other students from different institutions.
5.3 Recommendation:
TO SIWES
1. The SIWES should endeavor to pay the students industrial visits regularly to ensure that the
students are being trained as expected and not used for purposes other than why they are there.
They should also ensure that the environment is conducive for learning and pay the students
allowances as when due to motivate the students.

59. 59
2. The training should be well coordinated so that undergraduates can be exposed to the actual
work experience taking place in their respective fields.
3. The Institution should also help in securing placement for students.
TO BIORAJ
1. Regular maintenance of instruments and apparatus should be carried out in order to keep
them in good condition
2. A more efficient method should be devised for the disposal of waste chemicals used and
workshops should be organized from time to time in order to sensitize workers of the importance
of taking safety precautions when working in the laboratory.
3. BIORAJ should endeavor to organize seminars for their SIWES student intakes in order to
get them familiar with the processes of the laboratories before they start working in the
laboratories because each student has different level of exposure
5.4 PROBLEMS ENCOUNTERED DURING THE PROGRAMME.
 Distance: It takes a lot of resources and time to get to my place of attachment from my
place of abode. This contributed to poor state of health as I straggle to wake up early to
meet up with 7am being their startment time.
 Having less time for myself as the company Operates from Monday to Friday without
observing public holidays.
 No compensation from the company
