Assessing the photometric and wavelength performance of UV/VIS spectrophotometers is a necessary part of keeping your laboratory in accordance with GLP-, European Pharmacopeia (UP) or United States Pharmacopeia (USP) standards.
The spectral bandwith (SBW) refers to the physical slit-width of the spectrophotometer's monochromator, which has a direct impact on the instrument's resolution. In turn, spectral resolution is the ability to resolve two neighbouring peaks. Reconciling the resolution is an integral component in getting accurate wavelength and photometric readings on your spectrophotometer.
Recognizing the need for periodic assessment of SBW and pursuant to EP and USP requirements, FireflySci has expanded its range of calibration products to include this Toluene in Hexane standard.
Please note that this standard must be recalibrated annually according to NIST guidelines.
