Tenax-A加装活性炭采集TVOC

Tenax-A Installation of Activated Carbon Capture TVOC

通常采集空气中TVOC的采样管内装填的是Tenax-A一种填料,采集苯系物的采样管填充的是活性炭。只装Tenax-A一种填料的TVOC采样管的缺点是对高沸点的VOC采集效率高,但对低沸点的TVOC如三苯等采集效率低[5],我们在市售的TVOC采样管中加装活性炭,提高了对低沸点VOC的采集率,使得分析结果更加准确。

Usually collected in the air TVOC sampling tube is filled with a filler Tenax-A, the collection of benzene series sampling tube is filled with activated carbon. Only a Tenax-A filler TVOC sampling tube is VOC acquisition efficiency of the high boiling point is high, but the low boiling point such as TVOC three benzene collection efficiency is low, we added the sampling tube of activated carbon in commercially available TVOC, improve the low boiling point VOC acquisition rate, makes the analysis results more accurate.
