Abstract: A sorbent holder system that stores or transports a sorbent holder is provided. The sorbent holder system comprises a sorbent holder that holds sorbent material which is capable of sampling air or gas. The sorbent holder system also comprises a cleansing element which is separate from the sorbent material. The cleansing element is capable of absorbing or adsorbing at least one contaminant during storage or transportation of the sorbent holder whereby contamination of the sorbent material by the at least one contaminant is reduced or eliminated. Increased accuracy of sorbent analysis due to reduction or elimination of undesired contaminants from the sorbent during storage or transport of the sorbent holder is therefore achieved.

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.
