Advantages of methane non methane total hydrocarbon analyzer products：

Power on self-test functionEquipped with a self diagnostic function upon startup, allowing users to quickly identify the cause and location of instrument malfunctions,

One click reverse control：Networked data communication and remote control reverse control function.

Gas flow processUsing double column, single valve, and blowback technology, the content of methane and non methane total hydrocarbons can be analyzed in one injection. The external standard calculation method is adopted, and the results are accurate and reliable.

Automatic sampling systemThe sample is sucked into the quantitative ring by the pump, and the automatic valve is switched to complete the injection.

Automatic valve cutting completion systemSwitching the valve, the sample enters the chromatographic column with the carrier gas, separating methane and non methane hydrocarbons. When methane flows out of the chromatographic column and enters the detector for detection, switching the valve carrier gas back blows the chromatographic column to form a combined peak of hydrocarbon compounds (non methane total hydrocarbons) inside the column
