STARNA, REFERENCE MATERIALS Holmium Oxide - UV and Visible Wavelength

Holmium Oxide for UV and Visible Wavelength Holmium Oxide - UV and Visible Wavelength Description: Holmium oxide (4% m/v) in 10% v/v perchloric acid. Primary Usage: Assessment of wavelength scale accuracy in both UV and visible regions. Useable range: 240 nm to 650 nm, instruments with spectral bandwidth of less than 3 nm. Physical Configuration: Far UV quartz cells that have been permanently heat sealed. Typical values obtained: Holmium Oxide - UV and Visible Wavelength The use of holmium oxide solvated in perchloric acid is an established and well recognised method for the validation of the wavelength scale of a spectrophotometer in the UV and visible regions. When prepared in perchloric acid, holmium oxide gives a spectral scan containing a series of characteristic peaks. However, these values are dependent and will vary with the spectral bandwidth of the measuring instrument (NIST Special Publication 260-120) RM-HL: (see MSDS) Consists of: one sealed cell, with certified peak at spectral bandwidth values of 0.10 nm, 0.25 nm, 0.50 nm, 1.00 nm, 1.50 nm, 2.00 nm and 3.00 nm.
