Description

The ability to analytically quantify H2S (hydrogen sulfide) in non-volatile liquids, such as naphtha, water, crude oil (light, medium & heavy), and gasoline, are enhanced with the Sample Transfer Stripper S.T.S. Membrane Technology (Patent # 5,448,922) and ASTM approved radiometric colorimetric technology methods offered by Analytical Systems International.

The principle of operation requires a continuous free flowing liquid sample into a heated oven where the Sample Transfer Stripper (S.T.S) unit separates the liquids from the H2S gas sample. An H2S free air or nitrogen carrier then sweeps the H2S gas sample to the H2S analyzer for quantitative analysis in ppb, ppm, and up to saturation levels. A liquid validation by Perm Tube (Patent # 5,156,334) is optional. The detection technology is based on chemically specific density changes. The sensing tape utilized in this analyzer is the only detection method that is absolutely specific to H2S. Optical illumination & detection are integrated for maximum resolution accuracy. The electrochemical detection method is also available. Economic payout is increased because of this automated continuous process or laboratory analyzer.
