UV-Visible spectroscopy is a well-established analytical technique used in the development of active pharmaceutical ingredients, quantification of impurities, dissolution testing, and quantification of nucleic acids and proteins in pharmaceutical development.
For UV-Visible spectrophotometers in regulated laboratories, performance verification (PV) at installation and at set intervals thereafter is needed, however, the selection of standards for use in PV testing can be challenging.
- Wavelength accuracy and repeatability
- Absorbance accuracy, repeatability and linearity
- Stray light
- Resolution
