Tenax-TA热解吸型TVOC采样管

Tenax-TA采样管吸附剂化学名：2,6二苯呋喃多孔聚合物，表面积35m2/g；孔体积2.4cm3/g；平均孔径200nm；密度0.25g/cm3
内装美国原装进口Tenax-TA吸附剂，用于室内空气中总挥发性有机物（TVOC）的采集。
常用的规格有：6*150mm，6*200mm。其他规格可定做。

直型玻璃管：长度150㎜ 内径4mm 外径6mm 填充物质量200mg

    直型不锈钢：长度150㎜ 内径5mm 外径6mm 填充物质量200mg

U 型不锈钢：长度150㎜ 内径5mm 外径6mm 填充物质量200mg

Tenax采样管作为采集室内空气中TVOC的采样管，经过解吸或长时间存放后，吸附剂中会残留或吸附部分杂质，影响吸附管内吸附剂的性能，使用前必须进行活化再生处理。按照现有的活化规程，将吸附管置于320度恒温炉中，通入40ml/min流量的高纯氮气，直用气象色谱仪检测吸附管中无杂质峰为止。活化过程需要6~8小时方可满足分析，测试要求，成本高、效率低，无法满足日常检测工作的需要。而利用热解吸的吹扫功能，选择合适的洗脱剂，可以实现对Tenax-TA采样管的快速活化。

Tenax-TA thermal desorption TVOC sampling tube

Tenax-TA sampling tube adsorbent Chemical name: 2,6 Dibenzofuran porous polymer, surface area 35m2 / g; Pore volume 2.4cm3 / g; Average pore size 200nm; Density 0.25g / cm3
Contains the United States imported Tenax-TA sorbent for indoor air total volatile organic compounds (TVOC) collection.
Commonly used specifications are: 6 * 150mm, 6 * 200mm. Other specifications can be customized.

Straight glass tube: length 150mm diameter 4mm diameter 6mm filler quality 200mg

Straight stainless steel: length 150mm diameter 5mm diameter 6mm filler quality 200mg

U-type stainless steel: length 150mm diameter 5mm diameter 6mm filler quality 200mg

Tenax sampling tube is used to collect TVOC sample tube in indoor air. After desorption or storage for a long time, some impurities will be left or adsorbed in the adsorbent, which will affect the performance of adsorbent in adsorption tube. In accordance with the existing activation procedures, the adsorption tube placed in a 320-degree furnace, the flow of 40ml / min flow of high purity nitrogen, until the gas chromatograph with no impurities in the absorption tube peak. Activation process takes 6 to 8 hours to meet the analysis, testing requirements, high cost, low efficiency, can not meet the needs of routine testing. The rapid activation of the Tenax-TA sampling tube can be achieved by selecting the appropriate eluent using the thermal desorption purge function.

Indoor air pollutants TVOC application spectrum is as follows
