Description & Principle of Operation CRUDE • WATER • AMINE • NAPHTHA • GASOLINE • DIESEL The ability to analytically quantify H 2 S in non-volatile liquids, such as naphtha, water, light crude oil, and gasoline, are enhanced with the Sample Transfer Stripper TM (Patented Membrane Tech- nology) and ratiometric colorimetric technologies offered by Analytical Systems International Keco (ASI KECO). The principle of operation requires a continuous free flowing liquid sample into a heater where the Sample Transfer Stripper TM (STS) unit separates the liquids from the H 2 S gas sample. An H 2 S free air or nitrogen carrier then sweeps the H 2 S gas sample to the H 2 S analyzer for quantitative analysis in ppb w, ppmw, and up to saturation levels. A liquid validation by PermTube TM is optional. The detection technology is based on chemically specific density changes. The lead acetate sensing tape utilized in our analyzers is the only detection method that is absolutely specific to H 2 S.

Description & Principle of Operation
CRUDE WATER AMINE NAPHTHA GASOLINE DIESEL
The ability to analytically quantify H2S in non-volatile liquids, such as naphtha, water, light crudeoil, and gasoline, are enhanced with the Sample Transfer StripperTM (Patented Membrane Tech-nology) and ratiometric colorimetric technologies offered by Analytical Systems InternationalKeco (ASI KECO).
The principle of operation requires a continuous free flowing liquid sample into a heater where theSample Transfer StripperTM (STS) unit separates the liquids from the H2S gas sample. An H2Sfree air or nitrogen carrier then sweeps the H2S gas sample to the H2S analyzer for quantitativeanalysis in ppb w, ppmw, and up to saturation levels. A liquid validation by PermTubeTM is optional.The detection technology is based on chemically specific density changes. The lead acetatesensing tape utilized in our analyzers is the only detection method that is absolutely specific toH2S. Optical illumination & detection are integrated for maximum resolution accuracy. Economicpayout is increased because of this automated continuous process or laboratory analyzer.
