Determination of Sulfur Forms and Total Sulfur Content in Propene with GC-SCD

Carbonyl sulfide in propylene can be detected using the technology of GC - SCD.Hydrogen sulfide contained sulfide and sulfide morphology,and according to all the total response value,the total sulfur content can be calculated. The method can detect the content of 10μg/kg following carbonyl sulfide and 20μg/kg following hydrogen sulfide. The same sample after 5 times repeated determination of hydrogen sulfide,carbonyl sulfide and the relative standard deviation of RSD≤2%,and total sulfur measurement results was consistent with that of GB/T 11141 measured.
