Continuous monitoring of non-methane total hydrocarbons from fixed pollution sources
Continuous monitoring of non-methane total hydrocarbons from stationary sources of waste gas Details:

Stationary phase: polymer pellet
Precolumn: 0.8m*1/8, PQ
Analysis column: 1.5m*1/8
Particle size: 60-80 mesh

Nonmethane hydrocarbons (NMHC)
Under the conditions specified by the HJ38 standard, the sum of other gaseous organic compounds other than methane is responsive on the hydrogen flame ionization detector, and the results are in terms of carbon unless otherwise stated.
3.2
Nonmethane hydrocarbons continuous emission monitoring system (NMHC-CEMS)
All equipment required for continuous monitoring of non-methane total hydrocarbon emission concentrations and emissions from fixed source exhaust gas, referred to as NMHC-CEMS.
3. 3
Analysis cycle
The time interval between two sets of measurements is given when the system is running continuously.
3.4
Response factor
In this standard, a hydrogen flame ionization detector measures the dimensionless ratio of the response of other gaseous organic compounds to the measured propane response.

每一根色譜柱經(jīng)嚴(yán)格測試

色譜柱種類全

的技術(shù)支持

多年積累豐富的色譜分析經(jīng)驗(yàn)和技術(shù)團(tuán)隊(duì)

：

采用的不銹鋼管、玻璃管和色譜填料制作各種填充色譜柱

如需要用不銹鋼過濾網(wǎng)作為柱兩端堵頭，請在訂貨時注明

若采用柱上進(jìn)樣，柱入口前端將留有6CM 的空間,

為防止色譜填料流出，柱兩端均用硅烷化玻璃棉封堵

若采用閥進(jìn)樣或非柱上進(jìn)樣的色譜柱，其柱入口處被填滿

可提供多種型號氣相色譜儀所用玻璃柱構(gòu)型

2mm內(nèi)徑玻璃柱管的入口處均設(shè)有斜面以利進(jìn)樣

每根色譜柱均經(jīng)過充分老化和嚴(yán)格質(zhì)量評價測試
