Abstract

PURPOSE: To improve the measuring efficiency and prevent a worker from being exposed to radiant rays, by charging and recovering a sample without breaking vacuum in a furnace tube, whereby the time for measuring evaporable impurities in the sample can be shortened.
CONSTITUTION: A sample is introduced into a feed mechanism 12 from an inlet 11. The inlet 11 is then closed to open a valve 9 so that the sample in the feed mechanism 12 enters a sample receiving section 10. The valve 9 is then closed. The pressure in the measuring system as a whole is reduced by a pump 18. The measuring system is made highly vacuous by operating pumps 26, 27, 29, and a furnace tube 3 is subjected to vacuum burning by heating the same at a high temperature by a heater 4. Valves 30, 36 are closed and pumps 40, 42 are operated to conduct measurement of blank gas with a pressure gauge 38. The valves 30, 36 are then opened to discharge the gas collection section 37. The valves 30, 36 are closed to introduce the sample in the sample receiving section 10 into a sample holder 25 in a Mo cylindrical furnace 2. The sample is heated at a high vacuum and a high temperature. The impurities in the gasified sample are collected in the gas collection section 37 by pumps 40, 42 and subjected to measurement.
