名称：GDX-502甲烷柱

规格：2m*1/8，60-80目

编号：20220630003

温度：250°C

应用：HJ-2017环境空气/固定污染源废气中总烃，甲烷，非甲烷总烃的测定 气相色谱法

浩瀚色谱（山东）应用技术开发有限公司采用美国环保署(EPA)推荐的TO14/15方法和自动监测测定了某化工园区空气中挥发性有机物(VOC)以及非甲烷总烃,测定结果显示化工园区空气中非甲烷总烃与VOC的定量关系可以通过有效碳质量浓度建立,即非甲烷总烃有效碳质量浓度和VOC有效碳质量浓度之和相等。并藉此定义总有效碳解析度(R)以表征空气自动监测选定项目对空气有机污染的覆盖率指标,计算结果表明该空气自动监测选定的11项指标平均可表征该区域空气有机污染的71%。

Name: GDX-502 Methane Column

Specifications: 2m*1/8, 60-80 mesh

Number: 20220630003

Temperature: 250°C

Application: HJ-2017 Determination of total hydrocarbons, methane, and non-methane total hydrocarbons in ambient air/stationary pollution source waste gas by gas chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopted the TO14/15 method recommended by the US Environmental Protection Agency (EPA) and automatic monitoring to determine the volatile organic compounds (VOC) and non-methane total hydrocarbons in the air of a chemical park. The measurement results show that the chemical park The quantitative relationship between non-methane total hydrocarbons and VOC in the air can be established by the effective carbon mass concentration, that is, the sum of the effective carbon mass concentration of non-methane total hydrocarbons and VOC effective carbon mass concentration is equal. And the total effective carbon resolution (R) is defined to represent the coverage index of air organic pollution by the selected items of automatic air monitoring. The calculation results show that the 11 indicators selected by the automatic air monitoring can represent the air organic pollution in the region on average. 71%.
