& HOW TO ORDER    
 

This material can be used to qualify the wavelength scale of HPLC Diode Array detectors that can accept a 10 mm path length spectrophotometer cell in the sample position.

The use of Erbium oxide solvated in perchloric acid for the validation of the wavelength scale of HPLC Diode array detectors is well documented. When prepared in perchloric acid, erbium oxide gives a spectral scan containing a series of 9 characteristic and well-defined peaks covering the wavelength range from 230 nm to 660 nm. In typical HPLC validation protocols (e.g Waters) the three peaks at 255, 379 and 522 nm are used.
