The detection of methane/non methane total hydrocarbons is carried out using dual valve dual column single hydrogen flame ionization detector (FID) technology, which conforms to national standards and has the advantage of comparable standard methods. The instrument adopts a high-temperature heat tracing sample transmission at 175 ℃ throughout the process, and high-temperature FID detection. After the sample is filtered by a built-in filter, it is collected into a quantitative ring. The samples in the quantitative ring are sent to the chromatographic column for separation through the action of carrier gas. The separated components are then sequentially detected by FID detector. During sample analysis, the total hydrocarbon content is detected by entering the FID detector through an empty column; The mixed sample gas of methane and non methane total hydrocarbons is separated by another chromatographic column. Within a specified time, methane first enters the detector through the chromatographic column to obtain its methane content. The non methane total hydrocarbons are then blown back out of the chromatographic column by switching the valve. The difference in the content of total hydrocarbons and methane is the non methane total hydrocarbon content.
