固定污染源废气中苯系物的测定专用高温柱HH-Benzene series - II

固定污染源废气中苯系物的测定专用高温柱HH-Benzene series - II 详细信息：

名称：填充柱
型号：HH-Benzene series - II苯系物
规格：2m*3mm，60-80目
zuigao使用温度：240°C

浩瀚色谱研制的苯系物专用柱在200度的使用温度下：苯，jia苯，乙苯，二jia苯，苯乙烯等依然可以分离，此款产品为浩瀚色谱的特色产品。

浩瀚色谱（山东）应用技术开发有限公司基于biao准DB31/933-2015附录E固定污染源废气苯系物的测定气袋采样-气相色谱法进行了验证探究实验,该方法标准曲线线性良好,相关性系数均高于0.998;重复性准确度测定情况良好,苯系物各组分RSD%在0.9%～5%之间,加标回收率在80%～99.999%之间。该方法操作简单、准确度高、精密度好,适用于固定污染源废气中苯系物的测定;但是由于气体样品本身性质的不稳定和考虑到气袋质量参差不齐,采集的样品应尽快分析,根据DB31/933-2015附录E要求,样品应在12 h内完成分析。

Special high temperature column HH-Benzene series - II for the determination of benzene homologues in waste gas from fixed pollution sources

Special high temperature column HH-Benzene series - II for the determination of benzene homologues in waste gas from fixed pollution sources Details:

Name: Filled Column

Model: HH-Benzene series - II benzene series

Specification: 2m * 3mm, 60-80 mesh

Zuigao service temperature: 240 ° C

The special column for benzene series developed by Haohan Chromatography can still be separated at 200 ℃: benzene, jia benzene, ethylbenzene, di jia benzene, styrene, etc. This product is the characteristic product of Haohan Chromatography.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has carried out validation and exploration experiments based on the determination of benzene homologues in waste gas from fixed pollution sources in Appendix E of the Biao standard DB31/933-2015. The standard curve of this method is linear and the correlation coefficient is higher than 0.998; The repeatability and accuracy of the determination are good. The RSD% of each component of benzene series is between 0.9% and 5%, and the recovery rate of standard addition is between 80% and 99.999%. The method is simple in operation, high in accuracy and good in precision, and is suitable for the determination of benzene series in waste gas from fixed pollution sources; However, due to the unstable nature of gas samples and the uneven quality of gas bags, the collected samples should be analyzed as soon as possible. According to Appendix E of DB31/933-2015, the samples should be analyzed within 12 hours.
