QUALIFICATION OF UV-VISIBLE SPECTROPHOTOMETER, FTIR, DSC, HPLCAnupriyaNR
Analytical method qualification consists of a simplified evaluation of a subset of validation characteristics with a goal to demonstrate that an analytical method is scientifically sound and suitable for its intended use. In contrast to validation, analytical method qualification is performed without predefined acceptability criteria. Qualification may be performed as a prerequisite to method validation, or when an assay for product knowledge has not yet been established as a test for a critical product quality attribute. Qualification of equipment is pre-requisite for validation of the process in which the equipment is being used. Many types of equipment have measuring devices on them. Calibration of measuring devices is a part of qualification. Calibration of measuring devices is important, as the data is often collected through them. If the data collected is not from measuring devices that have been calibrated, the data cannot be relied upon. Thus the whole validation exercise can be questioned.

Validation is the process of establishing documentary evidence demonstrating that a procedure, process, activity carried out in
testing and then production maintain the desirable level of compliance all stages.
The process of providing the analytical procedure is acceptable or its intended us.(ICH Q
A validation programme involves various components in pharmaceutical organisation related to process, equipment and product.
It is a regulatory requirement for pharmaceutical companies to perform Instrument Validation on all new instruments.
Instrument Validation requires detailed knowledge of the instrumentation system being validated and is therefore usually performed by the company supplying the instrument.
The objective of any chemical analytical measurement is to get consistent, reliable and accurate data.
Proper functioning and performance of analytical instruments and computer systems plays a major role in achieving this goal.
Therefore, analytical instrument qualification (AIQ) and calibration should be part of any good analytical practice.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

MANAGEMENT OF ATRIOVENTRICULAR CONDUCTION BLOCK.pdfJim Jacob Roy
Cardiac conduction defects can occur due to various causes.
Atrioventricular conduction blocks ( AV blocks ) are classified into 3 types.
This document describes the acute management of AV block.

Calibration
In measurement technology and
metrology, calibration is the comparison
of measurement values delivered by a
device under test with those of a
calibration standard of known accuracy.
3. VALIDATION
Validation is the process of establishing
documentary evidence demonstrating that a
procedure, process, or activity carried out in
testing and then production maintains the desired
level of compliance at all stages
4. DIFFERENCE BETWEEN BOTH
Calibration ensures that instrument or measuring
devices producing accurate results.Validation provides
documented evidence that a process, equipment,
method or system produces consistent results (in
other words, it ensures that uniforms batches are
produced)
5. PH METER CALIBRATION
pH meter calibration is a necessary step of using a pH meter
because of how the electrode changes over time.Your pH
electrode is designed to measure pH based off of slope and
offset (the Nernst Equation)
All pH meters require calibration and should be calibrated
anywhere from before every use to at least once a month.
6. PROCEDURE
CalibratingYour pH Meter. Place your electrode in the buffer
with a pH value of 7 and begin reading. Press the “measure”
or calibrate button to begin reading the pH once your
electrode is placed in the buffer. Allow the pH reading to
stabilize before letting it sit for approximately 1-2 minutes.
7. CALIBRATION OF WEIGHING BALANCE
Calibration is crucial to increasing a weighing scale or
balance's longevity. It is also a necessary process to
ensure valid data during rigorous testing.
Calibration of the reference weights is performed
every two years by an ISO 17025 accredited vendor.
Internal calibration daily , and predcision once a
month
8. PROCEDURE
Place 5 gm of weighing pan
Note the weight
Calculate the weight difference
Repeat the above steps using 50 gm and 100 gm
Record the weight by noting down in form
And for precision place 5 gm pan and repeat this 9 times
And note the results.
