A gas discharge lamp and photoionization sensor employing the gas discharge lamp. The lamp includes a housing containing a working gas sealed within the housing and a primary ultra-violet transparent window through a first longitudinal end of the housing. In a first embodiment the lamp includes an arched band of elastic getter material band with longitudinally extending diametrically opposed legs wedged within the chamber defined by the housing. In a second embodiment the lamp includes a second ultra-violet transparent window within the housing held into positon against the primary ultra-violet transparent window by an arched metal support band within the housing.

UV lamp

A reactor capable of near absolute catalytic conversion of at least one alternative compound containing a specified moiety into a select compound containing the specific moiety, and an analytical instrument employing the reactor. The reactor including a catalytic element configured and arranged for fluid contact with a test fluid and a reactant, with at least 90% of the surface area of the catalytic element located within a thermal target zone in the reaction chamber of the reactor.

A gas discharge lamp, photoionization sensor employing the gas discharge lamp, and method of manufacturing the lamp. The lamp includes a longitudinally extending strip of getter within the housing. The method of manufacture includes the steps of (i) obtaining a glass tube, (ii) constricting the tube intermediate the longitudinal ends to divide the bore into first and second chambers in fluid communication with one another through a passageway in the constriction, (iii) attaching an ultraviolet transparent window over the open end of the first chamber, (iv) inserting a strip of getter into the first chamber through the passageway in the constriction, (v) purging the first chamber with a noble gas, and (vi) heating the tube at the constriction to detach the first chamber from the second chamber and seal the constricted end of the first chamber.

A sensor for detecting volatile organic compounds in ambient air by positioning a detection cell adjacent a gas discharge device to cause molecules of organic compounds to become ionized, and applying an electric field across the collection cell to attract ions and free electrons formed in the cell to develop a current, and amplifying the current magnitude so created.
