General description
Consisting of :
Holmium oxide in perchloric acid (667-UV5, wavelength 241; 287; 361; 536; 640 nm)

Holmium oxide dissolved in perchloric acid is highly suitable for checking the wavelength accuracy of spectrophotometers both in the UV and the visible range. It shows a spectrum with a multitude of highly defined peaks. The heights and positions of these peaks are dependent on and will vary with the chosen slit width of the measuring instrument.
