H2S in Water Analyzer: The ability to analytically quantify H2S in Water online is enhanced with the Sample Transfer Stripper (exclusive ASI Membrane Technologies) and the advanced electrochemical H2S sensor or rateometric-colorimetric H2S detector technologies offered by Analytical Systems Keco.
Economic payout is increased because of this automated and continuous process monitor. The most effective process for measuring H2S in water involves representatively stripping the H2S vapor from the water for precise measurement in the gas phase.
Direct optical measurement of H2S in the water is plagued by high routine maintenance and recalibration procedures. Analytical Systems utilizes the state-of-the-art Sample Transfer Stripper (STS) with exclusive ASI Membrane Technologies to efficiently and reliably separate the H2S from the water sample for measurement by the advanced electrochemical sensor or rateometric-colorimetric H2S detector.
The STS is a very simple device that provides an ultra-clean and dry sample to the detector for analysis. This results in radically reduced maintenance requirements when compared to direct optical measurement techniques. The principle of operation requires a continuous free-flowing water sample into the heated compartment where the STS unit separates the H2S from the water sample. An H2S free air or nitrogen carrier then sweeps the H2S gas sample to the H2S detector for quantitative analysis in PPBw, PPMw, and up to saturation levels.
ASI offers two detection technology choices for H2S measurement in water: The ASTM approved rateometric-colorimetric tape detector (Model 205P) and the Electrochemical Cell (Model 204H).
