Starna Toluene in Hexane Reference

 

.  Toluene in hexane is widely used to qualify the spectral bandwidth (resolution) of UV spectrophotometers, and is accepted for this purpose by most Pharmacopoeias and standardisation bodies

. To comply with Pharmacopoeia requirements, the instrument to be tested should have a spectral bandwidth not exceeding 1.8 nm (EP), or 2.0 nm (USP)

 

 

The ratio of the peak maximum at 269 nm to the minimum at 267 nm gives a measure of the bandwidth of the instrument. Typical ratios for different bandwidths (at 20°C) are:
