Principle and structure of methane non methane total hydrocarbon analyzer
Widely used in scientific research institutions, university research institutes, factories, painting, spray painting, chemical industry, sewage treatment, urban environment, health law enforcement, environmental monitoring and other industries.
Characteristics of methane non methane total hydrocarbon analyzer:
1. Can be connected to external temperature, humidity, and pressure sensors.
2. The temperature, humidity, and pressure data of the tested environment can be manually entered.
3. Support temperature compensation to obtain accurate data in cold environments.
4. Support humidity compensation to obtain accurate data in high humidity environments.
5. Customizable preheating time for sensors.
6. Multiple calibration points can be established to make the detection results more accurate.
7. It can roll back the calibration history to prevent inaccurate detection caused by misoperation.
8. Temporary zero point technology can detect low concentration trace gases and is very suitable for use as a gas leak detector.
The principle and structure of the methane non methane total hydrocarbon analyzer are as follows:
Using external standard calculation method, the results are accurate and reliable. The sample is sucked into the quantitative ring by the pump, and the switching valve allows the sample to enter the chromatographic column with the carrier gas. Methane and non methane hydrocarbons are separated. When methane flows out of the chromatographic column and enters the detector for detection, the switching valve allows the carrier gas to blow back into the chromatographic column, causing the hydrocarbon compounds (non methane total hydrocarbons) in the column to form a peak and blow back to the detector for detection. This instrument can achieve online multi-point monitoring according to user needs.
