  There are two methods for measuring NMHC concentration, one is the subtraction method, and the other is the direct measurement method (also known as the "direct method").



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a direct gas chromatography method for the determination of non methane total hydrocarbons in ambient air. The sample is directly injected to determine non methane total hydrocarbons, without the need for subtraction, with high efficiency and satisfactory results.
