Wavelength Calibration Solution, Holmium Oxide in perchloric acid. 60 ml. Chemical Solutions brand. 1 EA.
Additional Info:
This wavelength calibration solution (WCS) is a replacement solution for the Chemical Solutions HSQ™, PQ™ or UV-vis qualification kits. Used for HPLC UV detectors or UV-vis spectrophotometers to qualify and calibrate wavelength detection accuracy.
Supplied in a 60ml plastic bottle, the WCS is 4% holmium oxide (HOX) in 10% perchloric acid and is manufactured to NIST Standard SRM-02034.
Holmium oxide is an internationally recognized wavelength calibration primary standard, supported by NIST and other standards organizations. It provides 14 official absorbance bands ranging from 241 nm to 41 nm. Using HOX with caffeine standards you will be able to calibrate your detector down to 205 nm.
