Portable gas chromatograph specialized analyzer for methane and non methane detection


What is?portable gas chromatograph？
Advantages of portable gas chromatograph:
1. Very simple and convenient to use. Traditional chromatography instruments have complex structures and large volumes, and must be installed in fixed locations. Portable gas chromatographs have strong mobility, can be analyzed anytime and anywhere, and are not affected by external interference, with strong anti-interference ability.
2. Carry it with you. This is the biggest advantage of portable gas chromatographs, as they are small in size, lightweight, portable, and do not incur any expenses. And the price is also very affordable, some customers call it a mobile gas chromatograph, and the car is equipped with a gas chromatograph.

portable gas chromatographMain composition structure:
Instrument host (including FID detector module, chromatographic column separation module, EPC flow control module, solid-state hydrogen storage bottle, battery), sampling pipeline (including heat tracing pipeline, sampling probe, filtration device), tablet computer.
Gas chromatograph analysis process: After the sample is imported into the portable non methane total hydrocarbon analyzer, it should be able to be quantitatively injected into both the total hydrocarbon detection unit and the methane detection unit (separated by a chromatographic column and entering FID detection), and the content of total hydrocarbons and methane should be measured simultaneously. The difference between the two is the content of non methane total hydrocarbons

portable gas chromatographOther application scope:

Applied in industries such as refining and petrochemicals, surface coating, textile printing and dyeing, printing and packaging, footwear, rubber and plastic products, synthetic leather, chemical fiber, artificial board manufacturing, furniture manufacturing, electronic component manufacturing, life services, industrial parks and their factory boundaries, and fixed emission sources.
The main field of gas analysis is the comprehensive analysis of sulfides in gases such as natural gas, coal gas, coke oven gas, liquefied petroleum gas, and food grade carbon dioxide
Gasoline analysis mainly includes: analysis plan for oxygen-containing compounds in naphtha; Analysis scheme for carbon number distribution of petroleum wax n-alkanes and non-n-alkanes; Analysis plan for determination of benzene and toluene content in gasoline; Naphtha PONA analysis plan;
Food industry: analysis solutions for magnesium stearate and carboxymethyl starch, etc; Analysis of sweetener, saccharin sodium, neotame and lactic acid in Baijiu; Trans fatty acid analysis protocol; Analysis plan for residual detection and analysis of solvent No. 6 in vegetable oil.

The advantage of methane non methane analyzer is that it can measure total hydrocarbons and methane in ambient air and fixed pollution source exhaust gas, and can automatically and continuously sample, monitor, and respond quickly. The sampling system and analysis system are maintained at a controlled high temperature throughout the process, effectively preventing sample condensation or loss, and achieving monitoring of total hydrocarbons/methane/non methane total hydrocarbons.
