规格：0.8m*1/8

型号：HH-NMHC-8

应用：非甲烷总烃直测法

非甲烷总烃一般指的是除了甲烷外的所有可挥发性碳氢化合物,的的超过一定的浓度,除了直接对人体造成危害外,在日照的情况下出现光化学烟雾,当前为直接的方法是气相色谱法,基于此,本文则论述了气相色谱法在非甲烷总烃测定中的具体应用。

针对传统的气相色谱法测定非甲烷总烃：分别测定甲烷和总烃，然后差减得到非甲烷总烃。此法操作复杂，费时费力，有时非甲烷总烃出现负值。

2021 new national standard non-methane total hydrocarbon column
2021 new national standard non-methane total hydrocarbon column Details:

Specification: 0.8m*1/8

Model: HH-NMHC-8

Application: Non-methane total hydrocarbon direct measurement method




Non-methane total hydrocarbons generally refer to all volatile hydrocarbons except methane, which exceed a certain concentration. In addition to directly causing harm to the human body, photochemical smog appears under sunlight. The most direct method currently is Gas chromatography, based on this, this article discusses the specific application of gas chromatography in the determination of non-methane total hydrocarbons.

For the traditional gas chromatography determination of non-methane total hydrocarbons: measure methane and total hydrocarbons separately, and then subtract them to obtain non-methane total hydrocarbons. This method is complicated to operate, time-consuming and laborious, and sometimes non-methane total hydrocarbons have negative values.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd., relying on strong scientific research capabilities, has successfully developed a chromatographic column for the direct determination of non-methane total hydrocarbons, with high column efficiency, symmetrical peaks, and satisfactory results.

Haohan Chromatography has mastered the core technology; Haohan Chromatography has continuously climbed to new heights of analytical technology.
