Abstract

The availability of a time base scanning device is of particular importance when one desires to measure the rate of absorption change as the sample undergoes chemical degradation. Studies of chemical reactions and hydrolysis and precipitation rates depend upon the observation of the rate of change of the sample absorptivity. The accurate recording of the noise spectra of the instrument's one hundred % and zero % base lines also calls for the use of a time drive device.
