Technical overview of the OMA H2S analyzer

The OMA H2S Analyzer employs UV-Vis spectroscopy for precise H2S measurement. This technology involves measuring the absorbance of ultraviolet and visible light by the sample. The analyzer’s xenon light source transmits light through the sample in a flow cell, with fiber optic cables carrying the signal.

This process results in a high-resolution absorbance spectrum, allowing for accurate H2S detection. The analyzer’s software, ECLIPSE, processes this data to provide real-time concentration readings. Its design ensures safety, with the sample fluid remaining outside the analyzer enclosure. This technical sophistication positions the OMA H2S Analyzer as a leading solution in gas monitoring.
