Monitoring hydrogen sulfide (H2S) levels is critical for air quality, safety and environmental professionals across a multitude of industries. Doing so helps prevent complaints, citations, penalties, corrosion, fires, illness, and even death.
A number of methods have been developed to measure trace levels of H2S
The most widely used measurement methods include gold film analyzers, SO2 conversion, colorimetric gas detection tubes, electrochemical detectors, and lead acetate cassette tape gas detectors. This paper will explain the advantages and disadvantages of each in order to assist air quality, safety and environmental professionals alike in selecting the H2S analyzer that best meets their unique needs.
Main considerations when choosing an H2S analyzer include desired detection level, accuracy of measurements, potential interferences, and level of maintenance required to ensure the equipment is working properly.
