1. 1 A Seminar as a part of curricular requirement for I year M.Pharm II Semester Presented by Ms. T.Jayasree (Reg.No 20L81S0709) Pharmaceutical Analysis QUALIFICATION OF GAS CHROMATOGRAPHY

2. 2 Qualification Gas Chromatography (GC) Design Qualification (DQ ) Installation Qualification (IQ) Operational Qualification (OQ) Performance Qualification (PQ) References Contents

3. 3 Qualification- It is defined as the “action of proving that any equipment works correctly and leads to the expected results”. Qualification is also part of validation and is product specific. Qualification is often a part (the intial stage) of validation ,but the individual qualification steps alone do not constitute process validation . Qualification

4. 4 There are four stages of qualification 1) Design Qualification (DQ) 2) Installation Qualification (IQ) 3) Operational Qualification (OQ) 4) Performance Qualification (PQ)

5. 5 validation and qualification are essentially components of the same concept. The term qualification is normally used for equipment , utilities and systems. Validation is used for processes. In this sense, qualification is part of validation. Relationship between validation and qualification

6. 6 GAS CHROMATOGRAPHY (GC)  

7. 7 Supplier must provide documented evidence that the product has been designed, developed and manufactured in a quality environment e.g. ISO 9001:2000 certification. Supplier must provide phone and on-site support in case of defects. Supplier must provide information through the internet on availability of new firmware upgrades. Design Qualification

8. 8 Equipment is compared as received with purchase order, including software, accessories, spare parts and consumables. Documentation checked for completeness of operating, maintenance instructions, standard operating procedures for testing and safety, validation certificates and health and safety instruments. Equipment is checked for any damage. The supplier’s instruction for installation is read . Installation Qualification

9. 9 The supplier’s safety instructions are read, if there are any. Hardware (computer, equipment, fittings and tubings for fluid connections, power cable, data flow and instrument control cables) is installed following the manufacturer’s recommendation. The instruments are switched on and ensured that all modules power up and an electronic self test is performed. Any deviations are recorded .

10. 10 Software is installed on computer following the manufacturer’s recommendation. Correct software installation is verified. A backup copy of software is made.

11. 11 Precision of peak retention times Precision of peak areas Operational Qualification Test procedure Acceptance limits Test frequency Five injections of a standard. Calculation of relative standard deviation. <1% RSD ( Relative Standard Deviation) Yearly Test procedure Acceptance limits Test frequency Five injections of a standard. Calculation of relative standard deviation . <2% RSD Yearly

12. 12 Test procedure Acceptance limits Test frequency Remarks Temperature in column oven is measured and compared with set point. ±1°C Yearly The temperature measurement device should be calibrated and traceable to a national standard. Accuracy of the temperature of the column oven

13. 13 Precision of heated zone temperature Test procedure Acceptance Limits Test frequency Remarks Actual temperature is measured and compared with set points at 50,70 and 90°C. 2°C Yearly The temperature measurement device should be calibrated and traceable to a national standard .

14. 14 Precision of injection Test procedure Acceptance limits Test frequency Five injections of a standard. Calculation of relative Standard deviation. <2% RSD Yearly

15. 15 Test procedure Acceptance limits Test frequency Blank solvent is injected after standard . Peak ratio is measured between blank and standard injection. <5% Yearly Carryover of Injection

16. 16 Solution A 10 ml of methanol, ethanol, acetone make upto 100ml with ethyl acetate. Solution B 15 ml of methanol, ethanol, acetone make upto 100ml with ethyl acetate. Solution C 20 ml of methanol, ethanol, acetone make upto 100ml with ethyl acetate. Solution D 25 ml of methanol, ethanol, acetone make upto 100ml with ethyl acetate. Solution E 30 ml of methanol, ethanol, acetone make upto 100ml with ethyl acetate. Performance Qualification Detector Linearity Detector linearity solutions:

17. 17 Procedure Acceptance Criteria Blank is injected followed by detector linearity solutions and the peak responses are recorded . A standard plot is drawn between the concentrations vs the peak responses. The plot should be linear and regression coefficient ( R 2 ) should not be less than 0.9999.

18. 18 The digital flow meter is connected to the detector outlet port. The carrier gas flow is set and wait till it reaches the set flow. The observed flow in replicate is noted. The procedure is repeated for other carrier gases such as hydrogen and air. The flow rate of carrier gas should be ±10% of set flow. Flow rate accuracy

19. 19 20ml of methanol, ethanol and acetone is transferred into 100ml volumetric flask and made up with ethyl acetate. Blank is injected followed by standard preparation in six replicates. The areas and retention times are noted down. The %RSD (Relative standard deviation) of retention time should not be more than 1.0% and peak area not more than 5.0%. System precision

20. 20 After GC is ready, the system is run up to 15 minutes through single run. When the run is completed noise and drift is calculated through software. The acceptance values are: a ) Noise not more than 100µV. b ) Drift not more than 2500µV/hr. Detector noise and Drift test
