Abstract
A sorbent-filled sample tube is mounted to an aspirating source using a sample tube holder that includes a compression fitting having a fitting body, a cap, and a ferrule. The fitting cap is extended as a torque tube that surrounds the sample tube and has a length approximately equal to that of the sample tube to thereby protect the sample tube from damage. The free end of the torque tube is formed as a thumb wheel for ease in inserting and removing the sample tube without the use of a wrench or other tool.
