Beschreibung

This Standard Reference Material (SRM®) is intended for use in the evaluation and calibration of the relative spectral responsivity of steady-state fluorescence spectrometers with a continuous excitation source and for determining the day-to-day or instrument-to-instrument intensity variations of a single or similar fluorescence instrument(s), respectively. A unit of NIST-2942 consists of a single cuvette-shaped piece of solid glass. This SRM is certified for the relative, corrected emission spectrum, E, in relative energy units from emission wavelengths ?EM = 320 nm to 430 nm at 1 nm wavelength intervals at a fixed excitation wavelength (?EX) of 310.1 nm.
