Atomic absorption spectrometers MGA series optical range expansion

The article is devoted to problems of Atomic Absorption Spectrometers optical range expansion to red. A problem of light irradiated by graphite furnace striking to detector is the main aim of this work. This problem is proper to all graphite furnace Atomic Absorption Spectrometers. This problem can be solved by Zeeman modulation polarization spectrometry, a version of atomic-absorption technique realized in MGA series spectrometers.
