What is the UV Cutoff and why do I need to know it?

UV Cutoff wavelengths for common solvents

Every solvent has its specific absorbance cutoff wavelength. Below this wavelength the solvent itself absorbs the light. When choosing a solvent be aware of its cutoff and where your desired analytes will absorb. If the wavelengths are close, choose a different solvent. The list below displays the UV cutoff wavelengths of common solvents.
