Abstract

1,186,168. Arc lamps. TAVKOZLESI KUTATO INTEZET. 17 April, 1967 [16 April, 1966], No. 17597/67. Heading H1X. A D.C. plasma jet device for spectroscopy comprises an anode 12 and a feeder head including a vertically extending tube cathode 13 adapted to guide the arc and plasma and fastened removably in a block 19, the block 19 and cathode 13 being at least partly surrounded by a bell 18 having a plasma outlet 16 aligned with an outlet of the cathode, a sample guide tube 17 protruding through a side wall of the bell 18, and a protective ring 20 being arranged around the cathode inside the bell. The ring 20 protects the blade 19 from contamination by powder or liquid samples introduced through the tube 17. The anode 12 is a graphite disc with a plurality of passages 34 arranged in a circle, and contains a replaceable filler 25. Gas samples may be introduced with an inert working gas through a plastics pipe 29. The anode and cathode assemblies are supported by watercooled copper discs 21 and 23 separated by stabilizing discs 14 and 15, and having holes 32 and 33 for bolting the assembly together.
