Product summary: Non-methane hydrocarbons (NMHC) usually refer to all volatile hydrocarbons (mainly C2 to C8) except methane, also known as non-methane total hydrocarbons. The NMHC in the atmosphere exceeds a certain concentration, which is harmful to human health, and can also generate chemical smog, which is harmful to the environment and humans. The standard for the concentration of non-methane total hydrocarbons in China's Integrated Air Pollutants Discharge Standard (GB16927-1996) is 5mg / m3. There are many ways to monitor NMHC in ambient air and industrial exhaust, but most countries currently use

VOC On-line Analyzer of Volatile Organic Compounds Non-methane Total Hydrocarbons

Non-methane hydrocarbons (NMHC) usually refer to all volatile hydrocarbons (mainly C2 to C8) except methane, also known as non-methane total hydrocarbons. The NMHC in the atmosphere exceeds a certain concentration, which is harmful to human health, and can also generate chemical smog, which is harmful to the environment and humans. 。 The standard for the concentration of non-methane total hydrocarbons in China's Integrated Air Pollutants Discharge Standard (GB16927-1996) is 5 mg / m 3 .

There are many methods for monitoring NMHC in ambient air and industrial waste gas. However, most countries currently use gas chromatography. Therefore, we use a two-column dual hydrogen flame ionization detector gas chromatography to measure the total hydrocarbon and methane content, respectively. The difference is the content of NMHC. The NMHC measured under specified conditions is the total amount of hydrocarbons other than methane that has a significant response to the gas chromatographic hydrogen flame ionization detector, in carbon.

。 Total hydrocarbons / non-methane total hydrocarbons / specialized gas chromatography system, mainly based on: HJ604-2011 "Determination of total hydrocarbons in ambient air by gas chromatography", HJ / T38-1999 "Determination of non-methane total hydrocarbons in exhaust gas from national pollution sources" "Gas Chromatography" and other standards, using a double hydrogen flame detector / dual-tube fixed-volume injection valve design; only one injection can analyze total hydrocarbons and non-methane total hydrocarbons, the detection concentration of 0.05mg / m 3 .
