GDX-502甲烷填充柱 改进非甲烷总烃测定方法
简单介绍
GDX-502甲烷填充柱 改进非甲烷总烃测定方法的详细介绍
改进非甲烷总烃测定方法 详细信息:
名称:甲烷柱
固定相:高分子小球
粒度:60-80目,80-100目
规格:5m*3mm
型号:GDX-502
应用:固定污染源废气及环境空气中甲烷,总烃,非甲烷总烃的测定 气相色谱法
非甲烷总烃测定是环境监测中的一项重要内容,通常采用气相色谱法完成,总烃和甲烷含量的差值便是非甲烷总烃具体含量。
滕州市浩瀚色谱仪器技术服务有限公司,采用5m的GDX-502填充柱通过设计实验并分析可知,总烃峰型异常与烃的衍生物和色谱柱类型有关,在改进时,氧峰干扰可用除烃空气消除,差值结果便代表非甲烷总烃含量,检出限测定应按EPA SW-846标准进行,而zui采样容器为PVF气袋,即可测定结果的精准性。
柱效高,完全克服了O2的干扰,峰型对称,结果准确。

Improved non-methane total hydrocarbon determination method
Improve the determination method of non-methane total hydrocarbons Details:
Name: Methane Column
Statio
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 statio
The determination of non-methane total hydrocarbons is an im
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 co
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
