Only perform the mathematical computations needed to construct this type of procedure. By NO means acquire any of these chemicals and equipment. The method is as follows. The sample is injected at a constant rate into a flowing hydrogen stream at 1100 degrees Celsius. Sulfur in the sample is converted to hydrogen sulfide.
Detection is by the colorimetric reaction of hydrogen sulfide with lead acetate paper.
A certified standard is then used for calibration. The following is an explanation on analyzers that detect hydrogen sulfide using the method of colorimetric reaction of hydrogen sulfide with lead acetate sensing tape. This type of detection technology is based on chemically specific density changes in the tape as it is exposed to the gas. This sensing tape is the only detection method that is absolutely specific to hydrogen sulfide. Trace Technology hydrogen sulfide detector can be utilized for total sulfur measurement by means of converting the entire sulfur content in a sample to hydrogen sulfide.
