Sorbent tubes are the most widely used collection media for sampling hazardous gases and vapors in air, mostly as it relates to Industrial hygiene. They...

which volatiles in the air were collected by diffusion onto tubes packed with a sorbent, which was then heated to release the volatiles into the GC system...

layer (which is affected by flow) from dominating diffusion. The tube is filled with sorbents depending on the chemicals or chemical groups being sampled and...
