Evolution Spectrophotometer Performance Verification Procedure

PURPOSE: To provide methods for verification that absorbance measurements at a single wavelength made using the Thermo Scientific Evolution Spectrophotometer are traceable to a national standard and that the instrument is performing within specified limits.

NOTE: Users sometime employ the term ‘calibration’, but the appropriate terminology for the process of testing that a spectrophotometer is performing within manufacturer specifications is called, ‘performance verification’ (P.V.).
