Tenax-TA adsorption tube sampling tube/TVOC sampling tube/thermal desorption tube Details:
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. studied the effects of changes in these conditions on the adsorption performance of Tenax-TA on benzene and TVOC by changing the amount of Tenax-TA adsorbent, sampling temperature, and sample collection volume. Experiments show that Tenax-TA adsorbent can accurately quantify benzene and TVOC in the air at the same time under suitable conditions.
American standard Tenax-TA adsorption tube, 1/4*3.5 inches; other specifications: 6mm*150mm, 6mm*90mm, can be customized according to requirements.

The established test method eliminates the problems of the adsorption of the container sampling method and the difficulty of the activated carbon sampling method, and directly uses the sampling tube equipped with 0.5g Tenax-GC to collect and concentrate the benzene, benzene and dibenzene in the atmosphere. After the sampling tube is connected to the analysis system, it is heated at 180°C, and the analysis components are introduced into the analysis system in full. When collecting 1 liter of gas sample, this method can measure 3 kinds of benzene series in the atmosphere at ppb level.
