For spectrophotometer calibration according to European Pharmacopoeia (Ph. Eur.)

• Absorbance control
• Testing of resolution power
• Stray light testing
• Wavelength accuracy testing

In the pharmaceutical industry, a regular check of UV/Visible spectrophotometers according to Ph. Eur. is mandatory. Even in other industries, researchers who are using UV/Visible spectrophotometers, and who are working according to e.g. GMP, GLP, USP or ISO guidelines, need to check and qualify their instruments on a regular basis.
