Abstract: An enclosure system for receiving a cable includes an enclosure having an inner chamber and an open position exposing the inner chamber and a closed position covering the inner chamber. A cable receiving port in a wall of the enclosure extends along a longitudinal axis from outside of the enclosure into the inner chamber. The cable receiving port is configured to receive a cable therein when the cable is advanced axially into the port without rotation of the cable when the enclosure is in the closed position. A mating member is associated with the cable receiving port that limits rotation of the cable when the cable is advanced axially into the port. An axial retention member is associated with the cable receiving port that limits axial movement of the cable out of the port when the cable is advanced axially into the port to a lock position.

Abstract: A filed portable analyzer capable of performing both the sampling and analytical procedures required by U.S. EPA Method 25 utilizing a small volume injection of sample onto a cryotrap cooled by a Stirling linear drive charged with helium to replace the field sampling condensate trap. The cryotrap is followed by the specified sorbent column/traps to ensure precise compatibility with prior reported compliance test results. The analytical system utilizes an oxidation catalyst and reduction catalyst to remove the potential for differing response factors on the FID from different compounds.
