Abstract
An encapsulated sorbent tube includes a sampling sorbent tube having an open end and containing a sorbent material therein enclosed within an independent encapsulation element that has a body portion and an end portion. The body portion of the encapsulation element has an inner diameter greater than the outer diameter of the sampling sorbent tube sufficient to accommodate the sampling sorbent tube therein. The end portion of the encapsulation element is formed and defined by the longitudinal length of the encapsulation element in excess of the sampling sorbent tube, and includes a proximal frangible element and a distal closure seal, each being independent of and separated from the sampling sorbent tube.
