Description

UV-VIS internal standards allow the user to accurately measure the concentration of their samples by directly comparing the absorbance of their compounds against that of the internal standard.

SPEX Certiprep™ offers eight different standards that cover a wide range of wavelengths (270 to 627 nm). After the user takes a UV-VIS spectrum of their sample, they can find a region in the spectrum that doesn’t absorb, and then select the corresponding internal standard, and rerun the spectrum.
