Chromatography is a separation technique used to separate and analyze the components of a mixture. It involves the distribution of the components between two phases: a mobile phase and a stationary phase. The different affinities of the components for these phases lead to their separation based on their physical or chemical properties.

It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

INTRODUCTION
HPLC stand for “ High-performance liquid chromatography” ( sometimes referred to as High-
pressure liquid chromatography).
HPLC is a powerful tool in analysis, it yields high performance and high speed compared to
traditional columns chromatography because of the forcibly pumped mobile phase.
HPLC is a chromatographic technique that can separate a mixture of compounds.
It is used in biochemistry and analytical chemistry to identify, quantify, and purity the individual
components of a mixture.
Chromatography: physical method in which separation of components takes place between two
phases stationary phase and mobile phase.
Stationary phase: The substance on which adsorption of the analyte (the substance to be
separated during chromatography) takes place.it can be a solid or a solid liquid combination.
Mobile phase: solvent which carries the analyte (a liquid or gas ).
3. z
PRINCIPLE
The principle of HPLC is based on analyte distribution between the mobile and
stationary phases. It is important to keep in mind that the sample’s different constituents
elute at different times before the sample ingredients’ separation is achieved. The
intermolecular interactions between molecules of the sample and packaging materials
determine their time on-column.
4. z
TYPES OF HPLC SEPARATIONS
There are following variants of HPLC, depending upon the phase system (stationary) in the process :
1. Normal Phase HPLC: This method separates analytes on the basis of polarity. NP-HPLC uses
polar stationary phase and non-polar mobile phase. Therefore, the stationary phase is usually silica
and typical mobile phases are hexane, methylene chloride, chloroform, diethyl ether, and mixtures of
these.
Polar samples are thus retained on the polar surface of the column packing longer than less polar
materials.
5. z
2. Reverse Phase HPLC: The stationary phase is nonpolar
(hydrophobic) in nature, while the mobile phase is a polar liquid,
such as mixtures of water and methanol or acetonitrile. It works
on the principle of hydrophobic interactions hence the more
nonpolar the material is, the longer it will be retained.
6. z
3. Size-exclusion HPLC: The column is filled with material having
precisely controlled pore sizes, and the particles are separated
according to its their molecular size. Larger molecules are rapidly
washed through the column; smaller molecules penetrate inside the
porous of the packing particles and elute later.
7. z
4. Ion-Exchange HPLC: The stationary phase has an ionically charged surface of
opposite charge to the sample ions. This technique is used almost exclusively with ionic
or ionizable samples.
The stronger the charge on the sample, the stronger it will be attracted to the ionic
surface and thus, the longer it will take to elute. The mobile phase is an aqueous buffer,
where both pH and ionic strength are used to control elution time.
8. z
Instrumentation of HPLC
As shown in the diagram, HPLC instrumentation includes a pump, injector, column, detector and
integrator or acquisition and display system. The heart of the system is the column where separation
occurs.
1. Solvent Reservoir: Mobile phase contents are contained in a glass reservoir. The mobile phase,
or solvent, in HPLC is usually a mixture of polar and non-polar liquid components whose respective
concentrations are varied depending on the composition of the sample.
9. z
2. Pump: A pump aspirates the mobile phase from the solvent resorvoir and forces it through the system’s
column and detecter. Depending on a number of factors including column dimensions, particle size of the
stationary phase, the flow rate and composition of the mobile phase, operating pressures of up to 42000 kPa
(about 6000 psi) can be generated.
3. Sample Injector: The injector can be a single injection or an automated injection system. An injector for an
HPLC system should provide injection of the liquid sample within the range of 0.1-100 mL of volume with high
reproducibility and under high pressure (up to 4000 psi).
10. z
4. Columns: Columns are usually made of polished stainless steel, are between 50 and 300
mm long and have an internal diameter of between 2 and 5 mm. They are commonly filled
with a stationary phase with a particle size of 3–10 µm .Columns with internal diameters of
less than 2 mm are often referred to as microbore columns. Ideally the temperature of the
mobile phase and the column should be kept constant during an analysis.
5. Detector: The HPLC detector, located at the end of the column detect the analytes as
they elute from the chromatographic column. Commonly used detectors are UV-
spectroscopy, fluorescence, mass-spectrometric and electrochemical detectors.
6. Data Collection Devices: Signals from the detector may be collected on chart recorders
or electronic integrators that vary in complexity and in their ability to process, store and
reprocess chromatographic data. The computer integrates the response of the detector to
each component and places it into a chromatograph that is easy to read and interpret.
11. z
Applications of HPLC
The information that can be obtained by HPLC includes resolution, identification
and quantification of a compound. It also aids in chemical separation and
purification. The other applications of HPLC include :
Food and Flavor:
1. Measurement of Quality of soft drinks and water.
2. Sugar analysis in fruit juices.
Environmental Applications:
1. Detection of phenolic compounds in drinking water.
2. Bio-monitoring of pollutants.
Pharmaceutical Applications:
1. To control drug stability.
2. Tablet dissolution study of pharmaceutical dosages form.
3. Pharmaceutical quality control.
