Reference Materials for the Calibration of UV/visible Light Spectrophotometers

Technical Guide 38 (Version 4 – December 2017)

This guide provides information about reference materials that can be used when calibrating or checking the performance of a UV/visible light spectrophotometer. The known absorbance of reference materials at particular wavelengths can be used to validate the scale of absorbance (photometric accuracy), the wavelength accuracy of a spectrometer and identify stray light problems.
