Note
ChromQuest has four calibration files to choose from. The HolmiumUV
file contains five wavelengths in the UV region while the other files, such as
Holmium12, use sets of wavelengths from both the UV and Visible wavelength
regions. The holmium oxide absorbance maxima are selected from a spectrum
published in “Holmium Oxide Solution Wavelength Standard from 240 to
640 nm - SRM 2034 (NIST Special Publication 260-54)”.
