A large number of diodes serving as detector features makes it doable for simultaneous checking of many absorbing parts at differing wavelengths, with little time and diminished cost expended on highly-priced solvents.
This features is important when reference expectations are unavailable for impurities and degradants
The detection limit for a refractive index detector is significantly reduce than UV-Vis and FLD, but you'll find programs wherever RIDs must be your 1st selection.
