應(yīng)用：固定污染源廢氣及環(huán)境空氣中甲烷，總烴，非甲烷總烴的測定  氣相色譜法


非甲烷總烴測定是環(huán)境監(jiān)測中的一項重要內(nèi)容,通常采用氣相色譜法完成,總烴和甲烷含量的差值便是非甲烷總烴具體含量。

Improved non-methane total hydrocarbon determination method
Improve the determination method of non-methane total hydrocarbons Details:

Name: Methane Column

Stationary phase: polymer pellets

Particle size: 60-80 mesh, 80-100 mesh

Specification: 5m*3mm

Model: GDX-502

Application: Determination of methane, total hydrocarbons and non-methane total hydrocarbons in stationary source waste gas and ambient air gas chromatography


The determination of non-methane total hydrocarbons is an important part of environmental monitoring, which is usually completed by gas chromatography. The difference between total hydrocarbon and methane content is the specific content of non-methane total hydrocarbons.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. uses a 5m GDX-502 packed column. Through design experiments and analysis, it can be seen that the abnormal peak shape of total hydrocarbon is related to the derivative of hydrocarbon and the type of chromatographic column. When improving, oxygen peak interference can be eliminated. Hydrocarbon air is eliminated, and the difference result represents the total non-methane hydrocarbon content. The detection limit should be determined according to the EPA SW-846 standard, and the best sampling container is a PVF air bag to ensure the accuracy of the measurement results.

The column efficiency is high, the interference of O2 is completely overcome, the peak shape is symmetrical, and the result is accurate and reliable.
Haohan Chromatography provides a complete range of chromatographic columns
