why water, methanol, ethanol ets solvents are used in UV SPECTRIPHOTOMETER for blank reading ?..

Answer / nabil

Methanol for example absorbs at wavelengths below nm, and
water below 190 nm if we use methanol-water mix as a blank
we would have to use a wavelength grater than 205 nm to
avoid false reading.
