3 Qualification: Action of proving and documenting that any equipment, utilities, and systems actually and consistently leads to the expected results Qualification should be completed before process validation is performed. stages of qualification Design qualification(DQ) Installation qualification(IQ) Operational qualification(OQ) Performance qualification(PQ) Introduction
4 Design qualification(DQ) Documented evidence that the premises, supporting systems, utilities, equipment and processes have been designed in accordance with the requirements of GMP. Installation qualification (IQ) Installation qualification should provide documented evidence that the installation was complete, satisfactory and operate in accordance with established specifications.
5 Operational qualification (OQ) Operational qualification should provide documented evidence that utilities, systems or equipment and all its components operate in accordance with operational specifications Performance qualification (PQ) Performance qualification should provide documented evidence that utilities, systems or equipment and all its components can consistently perform in accordance with the specifications under routine use. Test results should be collected over a suitable period of time to prove consistency.

12 Test procedure Acceptance limits Test frequency Absorption of 1.2% potassium chloride solution at 200 nm is measured against water. Absorption at 200 nm >2.0 AU Six months Stray light Test frequency :- six months Remarks :- Standard is traceable to national standard. Remarks :-Alternative standards: Sodium nitrite Sodium iodide. 12 Maximas of holmium perchlorate Stray light test with 1.2% KCl
13 Test procedure Acceptance limits Transmission of cuvette (water) against air. a) Quartz cuvettes: 85% at 220 nm 88% at 240 nm b) Glass cuvettes: 85% at 356 nm 88% at 650 nm Control of cuvette Test frequency :- six months Remarks :- Standard is traceable to national standard. Test procedure Acceptance limits Test frequency Spectrum of toluene is measured from 260 to 275 nm. Ratio of peak height to valley is calculated. Absorbance ratio peak to valley at 266/269 nm > 1.5 Six months Wavelength resolution
Performance Qualification Parameter Reason Procedure Wavelength calibration Critical to accuracy of results. Can be determined using only two calibration wavelengths, preferably bracketing the analytical wavelength. Photometric accuracy Critical to accuracy of results Can be determined for particular absorbance at particular wavelengths using calibrated filters or cuvettes filled with standard solutions. Critical to accuracy of results Can be determined by checking the accuracy of a number of normal absorbances across the desired absorbance range. Extrapolation beyond highest standard is inadvisable. Linearity in photometric response
15 Parameter Reason Procedure Signal to noise ratio Important for sensitivity a nd limit detection Can be determined from the response of a detector to a dilute standard solution and/or a blank. Stray light Important measure of healt h of whole system Record uncorrected spectrum in single beam mode for double beam instruments or with baseline correction switched off for single beam instruments. Cont…
16 Parameter Reason Procedure Importance for precise and accurate measurement of peaks including partially resolv e d, br o ad a n d asymmetric peaks- does it do its sums properly? Is the software fully and correctly loaded? Does manipulation and storage corrupt the raw data? Can be determined and verified using software packages or using reference materials. Where instruments are designed to accept checking using datasets, these should be used . Absorption Important for accuracy and precision of results, checks that the optical faces of the cell are parallel. Can be determined by filling the cell with water, measuring at required wavelength(s), using air as the reference and repeating the process after rotating the cell through 180°.
