"Methanol, for example, absorbs at wavelengths below 205 nm, and water below 190 nm.
If you were using a methanol-water mixture as the solvent, you would therefore have
to use a wavelength greater than 205 nm to avoid false readings from the solvent."
They only mention one wavelength. Is that typical? Would a spectrometer
looking through the HPLC column output be something new?
