Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. uses GC-FPD technology to detect sulfides such as carbonyl sulfur and hydrogen sulfide in propylene. At the same time, according to the response value of sulfides, the content of each sulfide and total sulfur content. This method can detect carbonyl sulfide with a content below 10μg / kg and hydrogen sulfide with a content below 20μg / kg. The same sample is repeatedly tested 5 times. The relative standard deviation of the carbonyl sulfur and hydrogen sulfide is RSD ≤ 2%. The results of T11141 method were consistent.
