Buy on-line, White Photonics offers Starna NIST Traceable spectrometer reference standards in the Ultra Violet (UV) spectrum.
The UV Stray Light Reference, NIST Traceable is made of materials with sharp cutoffs in transmission at specified wavelengths, NIST Traceable with UKAS ISO 17025 accredited certificate of calibration. Detection of stray light in the UV and Visible, with a usable range of 200nm to 390nm, depending on the material.
Potassium Dichromate solvated in dilute (0.001N) perchlorate acid has been found to be the best method for testing the absorbance scale and linearity of spectrophotometers in the UV.
For the measurement of this fundamental parameter, Starna® offers you the choice of either sealed cell, or filter materials. Please note that your selection process should not only include the wavelength(s) required, but also the spectral bandwidth (SBW) of your spectrophotometer.… Full Detail
This NIST traceable set of one blank and four increasing concentrations of Nicotinic Acid is unique in its ability to validate the Far UV absorbance scale of your instrument. It consists of 5 cells with the following materials:… Full Detail
The UV/Vis Holmium Oxide Wavelength Reference contains Holmium oxide (4%) in perchloric acid (10%) NIST Traceable with UKAS ISO 17025 accredited certificate of calibration. Its primary use is for the assessment of wavelength scale accuracy in both UV and Visible, with a usable range of 240nm to 650nm. This references contains a filled far UV quartz cell that has been permanently heat sealed
The Far UV Rare Earth Wavelength Reference uses Rare Earth sulfate (0.05%) in sulfuric acid (0.03%) sealed in a quartz cell, NIST Traceable with UKAS ISO 17025 accredited certificate of calibration. Its primary usage is to validate the Far UV wavelength scale of spectrophotometers, with a usable range of 200nm to 260nm, spectral bandpass of 3nm or less.
The Samarium Perchlorate for Spectral Resolution contains Samarium Perchlorate sealed in quartz cells, NIST Traceable with UKAS ISO 17025 accredited certificate of calibration. Its primary usage is used in the assessment of wavelength accuracy in both UV and Visible, resolving complex peaks, with a usable range of 230nm to 560nm.
The Benzene Vapor for Spectral Resolution is a 0.1ml Benzene in a vapor state sealed in a quartz cell by heat fusion. Its primary usage is to test the resolution at various bandwidths of grating based instruments in the UV, with a usable range of 270nm to 230nm.
The NIST Traceable Toluene in Hexane uses a quartz cell filled with Toluene in Hexane and permanently sealed, NIST traceable. The primary usage is to determination of bandwidth and resolution in the UV region, with a usable range of 267.0nm and 268.7nm.
