甲烷填充柱和总烃色谱柱
固定污染源有组织排放和无组织排放的非甲烷总烃(NMHC):指除甲烷以外的碳氢化合物(其中主要是C2～C8)的总称。大气中的NMHC超过一定浓度,除直接对人体健康有害外,在一定条件下经日光照射还能产生光化学烟雾,对环境和人类造成危害。
滕州市浩瀚色谱仪器技术服务有限公司用GC-气相色谱仪，甲烷填充柱和总烃色谱柱，配双氢火焰检测器、双不锈钢填充柱分析固定污染源排气中总烃、甲烷、氧峰从而得到非甲烷总烃(NMHC)含量。当色谱进样量为1.0 mL时,方法的检出浓度为4×10-2mg/m3,方法的定量检定浓度范围为0.12～32 mg/m3。

Methane packed columns and total hydrocarbon chromatography columns
Non-methane total hydrocarbons (NMHC), organized and unorganized emissions from stationary pollution sources: Refers to the general term for hydrocarbons other than methane (mainly C2 to C8). The NMHC in the atmosphere exceeds a certain concentration, in addition to being directly harmful to human health, it can also produce photochemical smog under sunlight under certain conditions, causing harm to the environment and humans.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. used GC- gas chromatograph, methane packed column and total hydrocarbon chromatography column, equipped with dual hydrogen flame detector and double stainless steel packed column to analyze the total hydrocarbon, methane and oxygen peaks in the exhaust of fixed pollution Thus, the content of non-methane total hydrocarbons (NMHC) is obtained. When the chromatographic injection volume is 1.0 mL, the detection concentration of the method is 4 × 10-2mg / m3, and the quantitative detection concentration range of the method is 0.12 ～ 32 mg / m3.
Total hydrocarbon column:
Stationary phase: Silanized glass beads
Specification: 1m * 3mm (inner diameter) (metric system, general domestic chromatography instrument configuration)
1m * 1/8 (Imperial system, generally imported chromatographic instrument configuration)
Methane column:
Stationary phase: GDX-104
Specifications: 3m * 3mm (inner diameter) (metric system, general domestic chromatography instrument configuration)
3m * 1/8 inch (inch system, generally imported chromatographic instrument configuration)
