Methanol, such as, absorbs at wavelengths down below 205 nm, and h2o beneath one hundred ninety nm. When you were using a methanol-drinking water combination since the solvent, you'll thus really have to use a wavelength better than 205 nm to stop Untrue readings from the solvent.A syringe pump can be employed for even larger control of stream leve
