PMF-6 气体六通阀的详细资料

气体六通阀
气体六通阀 详细信息：

六通阀是气相色谱仪的一种气路附件,通常和定量管配合,作气体进样阀使用。在气体样品进样量较大时,它可使样品定量准确,数据重复性好。

在实际分析中由于样品的气、液、固、状态不同,分析目的不同,要求不同,相应的用于气相色谱分析的进样方式也有所不同,而且进样系统种类繁多。应用六通阀定体积进样就是其中的一种,其特点为操作简便、快速,测定结果准确、,重现性小于0.5%,符合技术要求。


应用实例：非甲烷总烃应用

采用单一进样口六通阀进样， Porapak Q柱和空柱两根填充柱及一个FID检测器的气相色谱法测定无组织大气中甲醇、甲烷、总烃和非甲烷总烃，测定结果均符合大气污染物综合排放标准中无组织排放监控标准要求。方法低检出浓度分别为甲烷0.04 mg/m3，总烃0.04 mg/m3，非甲烷总烃0.06 mg/m3，甲醇2 mg/m3，且能保持良好的重复性，相对标准偏差均小于2%，满足检测的要求。该方法操作简单、灵敏且分离度好，具有较好的重现性和的准确度。

Gas six-way valve
Six-way gas valve Details:

The six-port valve is a gas path accessory of the gas chromatograph. It is usually used as a gas sampling valve in conjunction with a quantitative tube. When the gas sample injection volume is large, it can make the sample quantitative accurately and the data repeatability is good.

In actual analysis, due to the different gas, liquid, solid and state of the samples, different analysis purposes and different requirements, the corresponding sampling methods for gas chromatography analysis are also different, and there are many kinds of sampling systems. The application of a six-port valve for fixed-volume sampling is one of them. It is characterized by simple and fast operation, accurate and reliable measurement results, and reproducibility of less than 0.5%, which meets the technical requirements.


Application example: non-methane total hydrocarbon application

A single-inlet six-port valve was used for sampling, Porapak Q column and empty column two packed columns and a FID detector were used to determine methanol, methane, total hydrocarbons and non-methane total hydrocarbons in unorganized atmosphere by gas chromatography. The results were all Meet the requirements of the unorganized emission monitoring standard in the comprehensive emission standard of air pollutants. The lowest detected concentrations of the method were 0.04 mg/m3 for methane, 0.04 mg/m3 for total hydrocarbons, 0.06 mg/m3 for non-methane total hydrocarbons, and 2 mg/m3 for methanol. The method can maintain good repeatability, and the relative standard deviations are all less than 2%. , Meet the requirements of testing. The method is simple, sensitive and has good resolution, with good reproducibility and reliable accuracy.
