Description :
The petrochemical, gas processing, & gas pipeline industry has needed a quality and cost effective sensing tape for H2S and total sulfur analyzers. With over twenty-five years of experience in developing and manufacturing sulfur analyzers and associated parts and supplies, Analytical Systems International has met this need with a fully warranted H2S sensing tape.

The sensing tape is prepared by impregnating lead acetate and other essential components ( both inert and active) into the paper tape. This formula, the treating process, and the ambient conditions are all critical to the success of the manufacturing process. After completion of this process, the sensing tape is installed in an appropriate analyzer. Sample gas containing trace quantities of H2S passes through a flow meter and a humidifier and then across the treated paper tape. When the H2S comes in contact with the lead acetate treated tape, lead sulfide is formed H2S+ Pb+ H2O= PbS. This reaction gradually darkens the tape according to H2S concentration. The resulting darkening is detected by photocells and is proportional to the H2S concentration. The electronics system can then provide a quantitative output according to the H2S level.
