名称：毛细管柱

规格：30m*0.53mm

型号：HH-THC-30

应用：环境空气，非甲烷总烃，甲烷，总烃测定；固定污染源废气，甲烷，总烃，非甲烷总烃测定  气相色谱法

滕州市浩瀚色谱仪器技术服务有限公司，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的非甲烷总烃采样容器。

Improved non-methane total hydrocarbon determination method
Improve non-methane total hydrocarbon determination method Details:

Name: Capillary Column

Specification: 30m*0.53mm

Model: HH-THC-30

Application: Determination of ambient air, non-methane total hydrocarbons, methane, total hydrocarbons; determination of stationary source waste gas, methane, total hydrocarbons, non-methane total hydrocarbons, gas chromatography



Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., based on non-methane total hydrocarbon emission standards, analysis methods and actual monitoring conditions, defines non-methane total hydrocarbons, abnormal peak patterns of total hydrocarbons, oxygen peak interference, method detection limit determination and sampling container The problems in selection and other aspects were discussed. The results show that the derivatives of gaseous hydrocarbons belong to non-methane total hydrocarbons. Hydrocarbon derivatives and column types are the main reasons for the abnormal peak pattern of total hydrocarbons. Using hydrocarbon-removing air as a carrier gas can eliminate the interference of oxygen peaks. For the difference result, the detection limit should be determined according to the EPA SW-846 standard. The PVF air bag has a low background, good air tightness and chemical inertness, and is the best non-methane total hydrocarbon sampling container.
