бедерсіз спектр

бедерсіз спектр

A single beam spectrum acquired with no sample in the infrared beam. The purpose of a background spectrum is to measure the contribution of the instrument and environment to the spectrum. These effects are removed from a sample spectrum by ratioing the sample single beam spectrum to the background spectrum.
