Portable Non Methane Total Hydrocarbon Analyzer

　　Model 3010 Portable Non Methane Total Hydrocarbon AnalyzerThe use of a heated hydrogen flame ionization detector is a classic method for measuring volatile organic compounds (THC, VOC, TOC, NMHC). The advantage of this method is that it can accurately measure hot/wet gas samples, and the entire sampling and analysis process is maintained at a high temperature (191 ℃), which can effectively prevent the loss of hydrocarbons caused by the condensation of high molecular weight hydrocarbons in the injection pipeline.

Model 3010Portable total hydrocarbon analyzerThe scope of application is very wide, such as boiler flue gas detection, incinerator flue gas detection, and volatile organic solvent leakage detection. 3010 HFID has a good correlation with lipids, alcohols, esters, ketones, and aromatic compounds, and is a reliable classic method for detecting total carbon and hydrogen concentrations.

　　Principle of total hydrocarbon analyzer:

The absorption spectrum of each hydrocarbon is unique, so it can be used as a "fingerprint" characteristic to decompose (identifiable) compound components. By relying on the resolution of the system, the intensity of absorption is proportional to the concentration of molecules, which can be used to calculate the concentration of components.

　　Current Status of Non Methane Total Hydrocarbon Instruments at Home and Abroad

At present, the main detection method for total hydrocarbons is laboratory gas chromatography, which has technical advantages in accurate qualitative and quantitative measurement. However, due to the need to collect samples from the site in the laboratory for measurement and analysis, there is a significant lag in analysis and monitoring; Sample distortion that occurs during the sampling, transportation, and storage of samples can lead to deviations in monitoring results. To achieve true pollution prevention and control of environmental air or fixed pollution source exhaust emissions, it is necessary to have real-time understanding of the concentration and amount of VOCs emissions, and be able to achieve emission reduction accounting for pollution sources, especially key pollution sources. In addition, in environmental law enforcement testing and emergency monitoring, it is necessary to immediately obtain pollution data and measurement results on site in order to take corresponding control measures in a timely manner. Portable instruments are needed to achieve rapid measurement, which laboratory testing cannot meet these requirements. Therefore, high requirements have been put forward for the performance and quality testing of VOCs portable devices.
