Abstract

The invention comprises a chamber for spectrographic analysis of samples by irradiating the sample with light in a rare gas e.g. argon atmosphere. The sample holder acting as cathode, is connected to the negative pole of a current source and is held against one end of the chamber. The anode is hollow so as to carry gas to a small cell in front of the sample. The end of the anode facing the sample is held in an insulating sleeve in which it can be moved to and fro through a rack drive mechanism operated from outside.
