How to optmize the Detector 2
Slit Width
The detector has a variable slit at the entrance of the spectrograph. This is an
effective tool to adapt the detector to changing demand of different analytical
problems.
A narrow slit provides spectral resolution for analytes with very fine
structures in the absorbance spectrum. An example of such a spectrum is
benzene. The five main absorbance bands (fingers) are only 2.5 nm wide and
just 6 nm apart from each other.
