RA-915M Mercury Analyzer with new pyrolyzer PYRO-915 (with large optical length of analytical cell and heated windows of the analytical cell is developed for unique direct mercury determination (no pretreatment procedures required) in complex organic samples at the level of few mg/kg.

Using of RA-915M spectrometer with background correction and a developed two-chamber catalyst atomizer PYRO-915 allows direct analysis of complex-matrix samples.

Is based on the atomization of mercury contained in the sample in a thermal decomposition attachment PYRO-915 and subsequent measuring the absorption of the 254-nm resonance radiation by mercury atoms using Zeeman correction for background absorption.
