浩瀚PQ甲烷柱

浩瀚PQ甲烷柱 详细信息：

名称：甲烷柱
固定相：高分子小球
粒度：60-80目
型号：PQ
规格：2m*1/8
应用：环境空气/固定污染源废气/甲烷，总烃，非甲烷总烃的测定
适用于：安捷伦，赛默飞，瓦里安，布鲁克，PE，岛津

浩瀚色谱（山东）应用技术开发有限公司根据非甲烷总烃排放标准、分析方法和实际监测情况,对非甲烷总烃定义、总烃峰型异常、氧峰干扰、方法检出限测定和采样容器选择等方面存在的问题进行了探讨。结果表明:气态烃的衍生物属于非甲烷总烃,烃的衍生物和色谱柱类型是导致总烃峰型异常的主要原因,使用除烃空气作载气可消除氧峰干扰,非甲烷总烃为差值结果,应按照EPA SW-846标准测定检出限,PVF气袋本底低、气密性和化学惰性好,是zui佳的非甲烷总烃采样容器。

Thermo Fisher PQ methane column

Thermo Fisher PQ Methane Column Details:

Name: Methane column

Stationary phase: polymer beads

Granularity: 60-80 mesh

Model: PQ

Specifications: 2m*1/8

Application: Determination of ambient air/stationary pollution source waste gas/methane, total hydrocarbons, non-methane total hydrocarbons

Available for: Agilent, Thermo Fisher, Varian, Bruker, PE, Shimadzu

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. based on the non-methane total hydrocarbon emission standards, analysis methods and actual monitoring conditions, the definition of non-methane total hydrocarbons, abnormal peak shape of total hydrocarbons, oxygen peak interference, method detection limit determination and sampling container The problems of selection and so on are discussed. The results show that: the derivatives of gaseous hydrocarbons belong to non-methane total hydrocarbons, and the main reasons for the abnormal peak shape of total hydrocarbons are the derivatives of hydrocarbons and the type of chromatographic column. For the difference results, the detection limit should be determined according to the EPA SW-846 standard. The PVF air bag has low background, good air tightness and chemical inertness, and is the best non-methane total hydrocarbon sampling container.
