Non-methane total hydrocarbon analyzerUsing advanced chromatographic analysis technology principle, it has the advantages of accurate test, high precision, good stability, high sensitivity and strong anti-interference ability. It is widely used in petrochemical, industrial, waste gas monitoring, environmental monitoring, sewage treatment, biopharmaceutical, family environmental protection, school laboratory and other fields. Non-methane total hydrocarbons, benzene series, etc. Can monitor stationary pollution sources or unorganized benzene series. Non-methane total hydrocarbons, etc.

The working principle of non-methane total hydrocarbon analyzer:

For non-methane total hydrocarbons in the atmosphere, the instrument uses cutting back and hydrogen flame ionization detector (FID) technology to detect methane and non-methane total hydrocarbons. The sampling pump collects the measured sample into the quantitative ring and enters the chromatographic column for analysis under the drive of gas loading. Methane is first separated from the chromatographic column, enters the FID detector, and then switches the valve position to blow out the non-methane total hydrocarbon in the chromatographic column and sends it to the FID detector for detection.

The instrument features of non-methane total hydrocarbon analyzer:

1. Using cutting back blowing technology, the system flow path design is simple, and the methane and non-methane total hydrocarbons are directly measured;

2. The FID detector will automatically shut down the hydrogen after extinguishing the fire to ensure the safety of the system;

3. Using voltage flow control technology (EPC.EFC) to control carrier gas, air and hydrogen, with high precision and good repeatability;

4. The core components have high reliability and long service life.

The non-methane total hydrocarbon analyzer is used for mobile, rapid detection and reading of the concentration, temperature and humidity of the non-methane total hydrocarbon gas. HD color screen for real-time display concentration. It can detect NMHC concentration and gas leakage in pipelines, narrow spaces and atmospheric environments. It can detect a variety of 1000 gases and measure the purity of high-concentration nitrogen and oxygen gases.

Non-methane total hydrocarbon analyzerUsing PID optical ion sensor. The PID consists of an ultraviolet light source and an ion chamber. Positive and negative electrodes form an electric field in the ion chamber. The gas to be measured is ionized under the irradiation of the ultraviolet lamp to generate positive and negative ions, form a current between the electrodes, and amplify the output signal. PID has the advantages of high sensitivity, no poisoning, safety and reliability. It can detect 400 kinds of volatile organic gases.
