Analysis method of gas chromatography H2, ethylene, ethylene, and acetylene

First of all, it depends on whether you want to analyze whether constant or trace. If you are constant, you can cooperate with the six -way gas procedure valve+Q -pillar+TCD detector. If the trace is more troublesome, two detectors are required for one FID, one, one, and oneTCD, Shitong gas inlet isolation valve+Q -pillar+FID+TCD detector, of which FID is used to determine ethylene, ethylene, acetylene, TCD to test H2.]

Porapak is a filling column and the PLOT is a capillary pillar. As long as the Q -pillar can be
, if there is a CO, it is unchanged to make a frequent bright method, and if you do a trace amount, you will not work.After the CO is transformed into methane through FID, it is tested

PQ filling columns are not very good for the separation of ethylene and ethylene, and it is difficult to completely separate hydrogen and carbon monoxide. It is not possible to test carbon molecular sieves, the program heating or constant temperature conditions, and the detector configuration is fine.

Only the percentage concentration can be measured. If there is oxygen nitrogen in your appearance, the hydrogen on the Q pillar is difficult to quantify
