To provide a documented procedure for good Laboratory Practices.
SCOPE
This procedure is applicable for good Laboratory Practices to be followed at the quality control laboratory at XYZ Limited.
RESPONSIBILITY
Primary: Chemist-Quality Control department.
Overall: Manager Quality control department
PROCEDURE
The following types of laboratory facilities are necessary for assuring the quality of Active pharmaceutical products:
Premises:
- Quality control labs should be well designed, equipped, and maintained, and have sufficient space to suit the operation to be performed in them.
- There should be provisions for writing, recording, and storage of control samples, chemicals, and documents.
- A separate room is necessary to keep sensitive instruments free from temperature and humidity variations and dust particles.
Equipment:
- Quality Control labs should be fully equipped with appropriate instruments for the testing procedures.
- Instruments should be calibrated at suitable specified intervals of time and readily available. Records should be maintained of the same. The records should indicate the next calibration date.
- Defective equipment/Instrument should be withdrawn from use until the fault has been rectified.
Cleanliness:
- Quality Control labs should be kept clean in accordance with the written procedure.
- A written procedure for cleaning the glass apparatus for chemical assay should be available.
- Personnel should wear clean, protective clothing appropriate to duties being performed.
Sampling:
- Samples should be taken in such a manner that they are representative samples in accordance with their written sampling procedure. For this statistical control norms can be adopted
- The sampling procedure should include:
- Method of sampling.
- Equipment to be used.
- Amount of sample taken.
- Any special precautions or instructions to be followed.
- Raw materials shall be collected as per the lot numbers or batch numbers given by the manufacturer.
- Each container should bear a label indicating:
- Name of the material.
- Date of collection/receipt.
- Batch / Lot number.
- Name of the manufacturer and supplier.
- Date of manufacturing/expiry.
- Status label: ‘UNDER TEST’, ‘APPROVED’, AND ‘REJECTED’.
Documentation:
- It indicates the test procedure, specifications, standards, limits, and detailed analytical reports.
- Raw material analysis records indicate:
- Name of the material with code number and reference number.
- Date of receipt, date of sample collected, date of analysis, completion data
- Number of containers received and number of samples collected.
- Detailed analytical report indicating standards and specifications, status of sample, with approved signatures.
Finished product records indicating:
- Name of the material with code number and reference number.
- Date of receipt, date of sample collected, date of analysis, completion data.
- Detailed analytical report indicating standards and specification, status of sample, with approved signatures.
- Record of in-process materials/intermediates.
- Record of standard/normal solution indicating periodically its validity, with the date and authorized signature.
- Reference standard records determining the potency/purity periodically with date and signature.
- Records of water analysis used for analytical purposes.
- Control sample records showing its location, date of receipt, and quantity received.
- List of various chemicals used.
- Stability data of all products.
Instrumentation and Calibration:
- Analytical balances should be checked at least annually against weights traceable to the National Bureau of Standards Calibration.
- The accuracy of the calibration of the pH meter should be checked using known buffers.
- Spectrophotometers should be checked about their photometric accuracy, reproducibility, resolution, and wavelength.
- Thermometers should be checked against the Standard Thermometers of the National Bureau of Standards Calibration.
- Dissolution apparatus shall be checked for both physical and chemical calibration
- FTIR shall be checked for wavenumber accuracy and repeatability.
- HPLCs shall be checked for calibration of the Pump, detector, and injector calibration.
Controls:
- CHEMICAL: A specially prepared test solution should be used for checking the accuracy of various tests.
- Karl Fischer Moisture Test: Test one or more hydrated compounds to compare the theoretical water content obtained.
- Infra-red and UV Identity: Maintain spectra of each active ingredient of the reference standard.
- Checking all the manufacturing and in-process data along with the analytical data before the final release.
Specifications:
- Specifications approved by Quality Control should be available for:
- Starting material
- Finished products
- Packing material
- Intermediates.
Facilities:
- Fuming chamber/exhaust fan
- Cross ventilation/air conditioning facilities.
- Chemical and glassware storage.
- Fire extinguishers.
Training:
- Chemists, analysts, lab assistants, should be trained to know the importance and technical importance of all GMP norms.
