浩瀚色谱（山东）应用技术开发有限公司通过测定苯回收率的方法探讨了使用Tenax-TA吸附剂检测室内空气中苯浓度的影响因素,如样品浓度、Tenax-TA试剂重量、采样温度、采样流速、采样体积等。试验结果表明,在一定浓度范围内,样品浓度不影响苯回收率;采样流速对苯回收率影响较小;而Tenax-TA试剂重量、采样温度和采样体积对苯回收率影响显著。

Adsorbent detects the concentration of benzene in indoor air
The adsorbent detects the concentration of benzene in indoor air. Details:

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used the method of determining the recovery rate of benzene to explore the influencing factors of using Tenax-TA adsorbent to detect the concentration of benzene in indoor air, such as sample concentration, Tenax-TA reagent weight, sampling temperature, and sampling flow rate. , Sampling volume, etc. The test results show that within a certain concentration range, the sample concentration does not affect the benzene recovery rate; the sampling flow rate has little effect on the benzene recovery rate; while the Tenax-TA reagent weight, sampling temperature and sampling volume have significant effects on the benzene recovery rate.

1. Use with thermal desorption to collect TVOC in the air

2. Stainless steel material, 200mg packing

3. Conventional 6*150mm 6*90mm 6.35*89mm (American standard), 1/4*3.5 inches

4. Unconventional 6*90.6*110. 6*125.6*130 can be customized

5. When the filler TENAX-TA is adsorbed to a certain degree of activation, it cannot be used again when there are miscellaneous peaks!
