What is UV Cutoff?
The wavelength below which a solvent absorbs ultraviolet light too strongly to be used, conventionally where its absorbance reaches 1 AU in a 1 cm cell against water or air. Approximate values are 190 nm for acetonitrile, 205 nm for methanol and 330 nm for acetone. Solvents should be chosen with a cutoff well below the detection wavelength.
