Total Sulfur Gas Chromatography Analyzer for Natural GasGC-2010-KT

1. Method Overview: Trace sulfur in natural gas is determined by gas chromatography, which is widely used in China,Its measurement range is:0～10（g/m3）Using a flame photometric detector（FPD）Measurement. Adopting sample diversion technology.

2. Trace sulfur gas chromatography instrument analysis uses a highly sensitive flame photometric detector to detect organic and inorganic sulfur. Inorganic sulfur in natural gasH2S、SO2Organic sulfurCOS、CS2、CH3STotal sulfur is the sum of all sulfur contents and can be detected0.01ppm

3. Instruments and materials: gas chromatograph (with flame photometric detector); workstation; Standard gas.

4. chromatographic column Polytetrafluoroethylene column, long1Rice.

5. Measurement steps Introduction of standard gas: Inject the standard gas twice in a row, and the relative deviation between the peak heights of the two injections should not exceed1%Otherwise, for the third time, take the values of two consecutive repetitions that pass the repeatability test, and take the average as the calibration value. Introduction of sample gas: Connect the sample gas container to the injector, using at least equivalent valves and quantitative tubes20A six way valve for blowing and cleaning gas with a sample volume of multiple times. After stopping the blowing, switch the valve and perform quantitative calculation.6.The following is the detailed configuration of the instrument:
