Non-methane total hydrocarbon analyzers generally refer to all volatile hydrocarbons except methane. NMHC in the atmosphere exceeds a certain concentration. In addition to directly endangering human health, it can also produce photochemical smog under certain conditions, which is harmful to the environment and humans.

The non-methane total hydrocarbon analyzer adopts the principle of gas chromatography-hydrogen flame ionization flame ionization detector, which can quickly and accurately measure the total hydrocarbons in the exhaust gas and unorganized emissions of stationary pollution sources. Methane. Non-methane total hydrocarbons and other components. Device advantages: Ethernet connection for efficient remote access; enhanced user interface and large display; flash memory for storing more data and downloading software; improved electronic design and product versatility, improved layout, and easier maintenance of components. Widely used in chemical, paint, printing and dyeing, furniture manufacturing, automobile manufacturing, pharmaceutical and other industries.

The equipment is suitable for the detection of volatile organic pollutants in various industrial ambient air and stationary source exhaust gas, and can be widely used in stationary source emissions, thermal reactor emissions, combustion device emissions, volatile organic solvent leakage, automobile exhaust emissions, and ambient air Detection and pollution exhaust gas detection in the medical industry.

In the working process, high-temperature heat tracing sample transmission, high-temperature FID detection, built-in filter filtration, quantitative loop collection, quantitative loop samples are sent to the chromatographic column to separate non-methane total hydrocarbon analyzer, and the separated components enter the FID detector for detection in turn. In the process of sample analysis, the total hydrocarbon enters the FID detector through the empty column, separates the mixed sample of methane and non-methane total hydrocarbon through another chromatographic column, enters the detector through the chromatographic column within the specified time, and switches the non-methane total hydrocarbon through the valve. The difference between total hydrocarbons and methane is non-methane total hydrocarbons.

non methane total hydrocarbon analyzer:

1. The sample from injection to emptying, the whole process of high temperature, reduce the measurement error caused by sample loss;

2. Adopt more reliable and durable rotor valve to effectively avoid the micro-leakage problem in the analysis flow path;

3. Using DC heating, the temperature control is more stable, and the chromatographic quality is more accurate;

4. The high quality FID detector meets the standard requirements;

5. It has the function of automatic ignition and flameout to automatically turn off hydrogen, which is safer and more reliable.

6. Full electronic pressure control (EPC) can transmit various instrument measurement parameters at any time to meet the requirements of dynamic control;

7. Double valve switching is adopted to ensure the backflushing function of the chromatographic column and improve the service life of the chromatographic column, which has great advantages in the application of high boiling point and high concentration.
