Abstract
A method for determining an optical pathlength through a cuvette of a spectrophotometric apparatus includes obtaining a first single beam spectrum of a liquid zero-material at least in a first energy region in which the liquid zero-material absorbs at least a portion of incident optical radiation; obtaining a second single beam spectrum of a second liquid at least in the first energy region, the second liquid having a composition excluding the liquid zero-material and having no absorption of incident optical radiation in the first energy region; determining a dual beam spectrum of the liquid zero-material relative to the second liquid at least in the first energy region from the first and second single beam spectra; and calculating an optical pathlength through the cuvette based on processing spectral information obtained from the first energy region of the determined dual beam spectrum.
