The advantages of the well-known atomic absorption (AA) spectrometry are utilized to the full extent and the technique itself is brought to perfection in the MGA-915 Atomic Absorption Spectrometer and RA-915+ Mercury Analyzer to make them state-of-the art, convenient, accurate, and extremely sensitive instruments due to the use of the Zeeman atomic absorption spectrometry using high frequency modulation of light polarization (ZAAS - HFM).

The high sensitivity and selectivity of the instruments allow the requirements for the sample preparation and its weight to be made much more lenient. The polarization modulation device embodies novel proprietary design features and components.
