Calibration of UV Cabinet - Standard Operating Procedure

This SOP provides guidelines for calibration of UV Cabinet used in pharmaceutical quality control department. The prime purpose of this standard of procedure is to train individual to operate the UV cabinet with proper maintenance. The primary purposes of using UV cabinets are Chromatographic analysis by Ultraviolet fluorescence. Further, these Cabinets used for screening the Chromatogram by combines the both long and short wave UV Lights and the White Light in a compact tabletop unit. This develops a self-contained unit that helps to easy viewing and production of Chromatograms. The frequency of the process will be once in every 3 months. The desired wavelength will be 254nm. A 0.04%w/v sodium salicylate solution will be prepared in ethanol of 95% strength. From this solution, 5µ will be taken on silica gel and a diameter of 5nm will be taken. Further, for the observation process the distance between the lamp and plates under observation for pharmacopeial tests should be maintained as per the testing protocol.

2. Purpose: The UV cabinet is important equipment that is used in pharmaceutical quality control
department. This equipment emits UV light using, which, several quality related parameter are checked and
determined. The prime purpose of this standard of procedure is to train individual to operate the UV cabinet
with proper maintenance (ICH 2018).
3. Scope: The primary purposes of using UV cabinets are Chromatographic analysis by Ultraviolet
fluorescence. Further, these Cabinets used for screening the Chromatogram by combines the both long and
short wave UV Lights and the White Light in a compact tabletop unit. This develops a self-contained unit
that helps to easy viewing and production of Chromatograms (Syed et al. 2015). Furthermore, it also helps in
the general Florescence Studies. These Cabinets are made up of powerful UV Lights that denatures Nucleic
Acids in 5 to 30 minutes making them inappropriate for Amplification and Contamination of the PCR
reactions. These lights are controlled by timers and are inclusive of safety switches on the Cabinet
Doors through which putting on and off the UV lights are easier when opened to prevent user exposure
to UV light (Krzyścin et al. 2012).

5. Procedure:
 The frequency of the process will be once in every 3 months.
 The desired wavelength will be 254nm
 A 0.04%w/v sodium salicylate solution will be prepared in ethanol of 95% strength.
 From this solution, 5μ will be taken on silica gel and a diameter of 5nm will be taken.
 Further, for the observation process the distance between the lamp and plates under
observation for pharmacopeial tests should be maintained as per the testing protocol.
 The light should be capable of revealing without a doubt a standard spot of sodium salicylate.
 Further for the 369 nm wavelength, the above mentioned process will be repeated (Syed et al.
2015).
7. Distribution list:
 The quality control chemical department
 The microbiological quality control department
 The media preparation and raw material testing department
