Abstract
1,261,596. Discharge lamps. APPLIED RESEARCH LABORATORIES Inc. 16 June, 1969 [17 June, 1968], No. 30399/69. Heading H1D. Material to be analysed spectrochemically is injected through an inlet 24 into a gas flowing through a tube 26 along which an arc is maintained in a wall-stabilized state by dynamically cooling the tube. A working gas, e.g. argon is admitted through a port 16 to a chamber 10 having a window 14, e.g. of lithium fluoride and an outlet 12 cooled by liquid circulating in a passage 18 and serving as an anode between which and a cathode 30, e.g. a wire of 99% tungsten-1% thorium alloy, a wall-stabilized arc is maintained along the tube 26 which is cooled by liquid in a passage 27. The inlet 24 opens into a passage 22 in an insulating disc 20, e.g. of boron nitride. The material to be analysed may be a gas or submicron particles entrained in a carrier gas such as argon. An exhaust port 36 is provided. The arc may be struck by a high-voltage pulse or by a movable auxiliary electrode (not shown). In a modified arrangement (Fig. 2, not shown) for absorption analysis the passage 26 is extended to a second chamber similar to the chamber 10. A light source is mounted internally or externally of this second chamber.
