Trace total hydrocarbon chromatographic analyzerUsed for online monitoring of argon, nitrogen, oxygen, carbon dioxide, carbon monoxide, and total hydrocarbons in the air in industries such as petrochemicals, steel, and gas.

The trace total hydrocarbon chromatographic analyzer is designed and manufactured based on the principle of gas chromatography. As a process control instrument, its detection sensitivity is high, the results are directly displayed, and the signal can be transmitted remotely.

Product features of trace total hydrocarbon chromatographic analyzer:

1. It has the characteristics of unmanned operation, high sensitivity, and good stability. The detection signal can be directly read and displayed, and can also be transmitted remotely,

The two technical indicators fully meet the relevant provisions in the national standards.

The operation of the instrument requires the combustion of hydrogen gas and auxiliary gas air to form a stable hydrogen flame. The sample gas enters the flame at a fixed flow rate for combustion, generating an ion flow that is collected and detected.

Therefore, this instrument analyzes the total volatile hydrocarbons in the gas at room temperature.

The detection shows a minimum value of 0.1ppm and a maximum value of 200ppm.

Excessive total hydrocarbon content in liquid oxygen can cause explosions, so the air separation workshop attaches great importance to the analysis of hydrocarbon content in liquid oxygen, and it is necessary to choose a trace total hydrocarbon chromatographic analyzer
