ABSTRACT:
A preheating apparatus of an analysis apparatus for determining the in quantity hydrogen and carbon contained in a sample such as steel is employed to remove moisture adhered to a sample of the steel by spot-heating focused on the sample in a transparent bent tube which is turned one-half in its circumferential direction after completion of its preheating to make it possible for the sample to be transfered by gravity from the bent tube into a graphite crucible in which the sample is fused to extract hydrogen and carbon contained in the sample, so that the thus extracted hydrogen and carbon are determined.
