摘要： A denuder assembly is adapted for the collection and removal of a gaseous analyte from a sample gas. The denuder includes a housing including an internal cavity, a sample gas inlet fluidly coupled with a sample gas source, a denuder liquid inlet fluidly coupled with a denuder liquid source, a barrier sheet extending across the internal cavity and separating the internal cavity into a liquid reservoir and a gas flow-through channel fluidly coupled with and downstream of the sample gas inlet, and a denuder liquid disposed in the liquid reservoir and permeating the barrier sheet to coat the gas-channel surface of the barrier sheet thereby allowing the denuder liquid on the gas-channel surface to contact the sample gas flowing within the gas flow-through channel and allowing the analyte to diffuse through the barrier sheet into the liquid reservoir.

摘要： A wellbore fluid sampling apparatus includes an elongated barrel member having a chamber formed by a through flow passage opening from the bottom of the barrel member to a port in the barrel member. Spaced apart ball type valve closure members are connected to an actuating linkage comprising a rack and pinion mechanism connected to respective ones of the closure members. A cocking and retaining mechanism includes an actuating rod and a collet sleeve connected to the rack member and biased by a coil spring to move the rack member to simultaneously close both valves upon release of the collet sleeve from gripping engagement with the wall of the bore in a body member of the apparatus. In an alternate embodiment, the actuating member includes a part gripped by a stationary collet which may release the part upon movement of a sliding sleeve which is actuatable at will. The actuating member is connected to elongated cable traces which are operable to move the valves between open and closed positions. The ball valves include lateral ports for evacuating the closure member passages in the valve closed positions.
