667-UV6 Toluene in hexane liquid filter to check spectral resolution
The liquid filter toluene in hexan shows in its spectrum in the range between 265-270 nm one distinctive feature, with which the spectral resolution resp. the actual slit width of a spectometer can be determined according to the regulations of the European pharmacopeia and the US pharmacopeia.
Measurements of the spectral resolution are conducted against the reference filter 667-UV9 hexane, which is included in the delievery of each the filter set. The excecution of the measurement is the same for all band width. The wavelength range is scanned from 265nm to 270nm and the peak maxiumum and the peak minimum is to be determined. Afterwards the behavior in between the two values is calculated.
