GC-2010FType Trace Sulfur AnalyzerIt is an instrument with high sensitivity and selectivity for trace sulfur compounds, with high sensitivity, good stability, easy operation, and Chinese liquid crystal display. It is suitable for quantitative and qualitative analysis of sulfur compounds in natural gas, water gas, semi water gas, coke oven gas, petroleum processing by-products and other samples. In domestic refined benzene projects, the determination of trace thiophene has been widely used.

Precautions for operating a trace sulfur analyzer:

（1）To waitFPD detectorPart of the temperature rises above100After ℃ (approximately)1Hours are required to ignite the hydrogen flame, otherwise the detector will not be able to analyze the accumulated water.

（2）When aging a newly installed chromatographic column, the following steps should be taken:FPDDetach from the chromatographic column, otherwise solvent will enterFPDIt is possible to contaminate the detector and cause a decrease in sensitivity.
（3）Do not open the detector cover with the high-voltage power switch turned on to avoid aging of the photomultiplier tube.The voltage divider resistor on the pin of the photomultiplier tube has been properly connected during assembly, and generally should not be tampered with.
（4）When turning on oxygen or air, slowly increase it from small to large, and do not turn it up all at once to avoid accidents.
（5）When shutting down, first turn off the oxygen, then turn off the hydrogen, and then turn off them in sequence“high pressure”,“Column temperature”； After the testing room cools down to room temperature, turn it off“detecting chamber”； After the constant greenhouse cools down to room temperature, turn it off“amplifier”And behind it“power supply”Switch and carrier gas.
（6）To avoid the situation where the temperature of the constant temperature chamber exceeds the maximum temperature allowed by the chromatographic column, otherwise it will lead to detector contamination, decreased sensitivity, chromatographic column deterioration, increased sulfide adsorption loss, and ultimately inability to analyze.
