Tenax采样管 富集气相色谱法测定固定污染源废气的详细资料

富集气相色谱法测定固定污染源废气
富集气相色谱法测定固定污染源废气 详细信息：

由于生产和实验室环境的差异， Tenax-TA吸附剂制备和放置过程中所带来的污染各不相同，新充填的采样管在200°C条件下通氮气老化30min不但需要大量的高纯氮气，有时很难达到分析要求，这将直接影响着苯系物测定结果的重复性和准确性。同时由于每次只能处理一根采样管，对于大量分析工作将很难在较短时间完成。

浩瀚色谱（山东）应用技术开发有限公司针对现有Tenax-TA吸附剂处理过程的不足，研发一种环境空气中苯系物测定过程中使用Tenax-TA吸附剂的处理方法，一次可处理较大量的吸附剂，处理的 Tenax-TA吸附剂，具有测定结果重复性好，对苯系物的吸收效率高等优点。

Enrichment Gas Chromatography Method for Determination of Waste Gas from Stationary Pollution Sources
Enrichment Gas Chromatography Method for Determination of Waste Gas from Stationary Pollution Sources Details:

Due to the difference between the production and laboratory environment, the pollution caused by the preparation and placement of Tenax-TA adsorbent is different. The newly filled sampling tube is aged for 30 minutes under the condition of 200°C with nitrogen, not only requires a large amount of high-purity nitrogen , Sometimes it is difficult to meet the analysis requirements, which will directly affect the repeatability and accuracy of the benzene series determination results. At the same time, since only one sampling tube can be processed at a time, it is difficult to complete a large amount of analysis work in a short time.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a treatment method that uses Tenax-TA adsorbent in the determination of benzene series in ambient air to deal with the shortcomings of the existing Tenax-TA adsorbent treatment process, which can process a larger amount at a time The adsorbent, the treated Tenax-TA adsorbent, has the advantages of good reproducibility of measurement results and high absorption efficiency of benzene series.
