haohan一根填充柱测定非甲烷总烃应用赛默飞在线1.2m*1/8，60-80目

非甲烷总烃的主要来源
NMHC的来源非常广泛，可分为自然源和人为源：
自然源：植物释放、森林火灾、野生动物排放等。但这通常不是环境管理的重点。
人为源（主要管理对象）：
工业过程：石油炼制、化工生产（塑料、合成橡胶、树脂）、印刷、家具制造、涂料喷涂、电子工业等。
燃料燃烧：机动车、船舶、飞机等移动源的尾气排放；工业锅炉和民用炉灶的不完全燃烧。
溶剂使用：油漆、涂料、胶粘剂、油墨、清洗剂等的挥发。
石油和天然气的储存与运输：油品在储存、装卸过程中的挥发泄漏。
废弃物处理：垃圾填埋场、污水处理厂的挥发气体。

 

传统的做法是采用2根色谱柱，1个甲烷柱，1个总烃柱，分别测定甲烷和总烃，差减法得出非甲烷总烃，此法操作复杂，费时费力，效率低下，无法满足工业大规格生产检测的需要，使用受限。

 

浩瀚色谱（山东）应用技术开发有限公司，研制《单个色谱柱测定非甲烷总烃安捷伦6890》，此法只需要1个填充柱，即可直接测定非甲烷总烃的含量，不要差减计算，效率高，结果满意。

The main source of non methane total hydrocarbons
The sources of NMHC are very diverse and can be divided into natural sources and anthropogenic sources:
Natural sources: plant releases, forest fires, wildlife emissions, etc. But this is usually not the focus of environmental management.
Human source (main management object):
Industrial processes: petroleum refining, chemical production (plastics, synthetic rubber, resins), printing, furniture manufacturing, paint spraying, electronics industry, etc.
Fuel combustion: exhaust emissions from mobile sources such as motor vehicles, ships, and airplanes; Incomplete combustion of industrial boilers and civilian stoves.
Solvent usage: volatilization of paints, coatings, adhesives, inks, cleaning agents, etc.
Storage and transportation of oil and natural gas: volatilization and leakage of oil products during storage, loading and unloading processes.
Waste disposal: volatile gases from landfills and sewage treatment plants.
The traditional approach is to use two chromatography columns, one methane column, and one total hydrocarbon column, to measure methane and total hydrocarbons separately. The differential method is used to obtain non methane total hydrocarbons. This method is complex, time-consuming, labor-intensive, and inefficient, and cannot meet the needs of large-scale industrial production testing, which limits its use.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the Agilent 6890 method for the determination of non methane total hydrocarbons using a single chromatographic column. This method only requires one packed column and can directly determine the content of non methane total hydrocarbons without subtracting calculations. It has high efficiency and satisfactory results.
