The European Pharmacopoeia (Ph. Eur.) has standard norms for UV/Vis spectroscopy. Ph. Eur. methods for UV/Vis measurements are similar to those of USP, and both are based on the use of spectrophotometers to measure the absorbance of light at different wavelengths. The Ph. Eur. provides general chapters and monographs that describe approved methods, acceptance criteria, and allowable tolerances for UV/Vis spectroscopy. These standards help ensure the quality and consistency of medicines and other substances. Ph. Eur. standards also provide guidance on instrument calibration, maintenance, and performance verification, as well as on sample preparation and analysis. The following are the monographs that can be consulted to ensure compliance with Ph. Eur. standards in UV/Vis spectroscopy.
