Elder Scrolls Online will remove its subscription fee and will be free to play starting on March 17. Players can purchase the game now renamed The Elder Scrolls Online: Tamriel United at one time and continue playing it for free onwards.
NIST Traceable reference standards for verifying the wavelength accuracy of a UV/VIS spectrophotometer. All standards are stringently prepared according to NIST guidelines.NSG's solid-state standards never need to be replaced due to material aging and come with a unique lifetime warranty.IST Traceable reference standards for verifying the wavelength accuracy of a UV/VIS spectrophotometer.

Figure 1: Spectrum of a 1.95 x 10 -4 mol/L niacin solution in the ultra-violet wavelength region. Now, if scans are being performed on the sample and reference materials separately, what we must be most concerned with is the repeatability (precision) of instrument wavelength scale.hat we can see from the discussion above is that errors in the wavelength scale of a spectrophotometer can indeed have a significant impact on photometric measurements even when wavelength is not called out specifically as an acceptance criterion for the analytical result.
