Application: HJ/T 38-1999 Determination of non-methane total hydrocarbons in exhaust gas from stationary pollution sources-Gas chromatography

Non-methane hydrocarbons (NMHC) refer to the sum of volatile hydrocarbons (mainly C2-C8) other than methane, which has long been an important indicator of ambient air monitoring. GB16927-1996 stipulates that the factory boundary concentration standard of non-methane total hydrocarbons is 4 mg m-3, and "Gas Chromatography Method for Determination of Non-methane Total Hydrocarbons in Exhaust Gas from Stationary Pollution Sources" HJ/T 38-1999 describes the specific detection method.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. investigated the use effect of Agilent dual-valve dual-column gas phase system, and realized the rapid and accurate determination of non-methane total hydrocarbons in ambient air and pollution source waste gas.
