ABSTRACT OF THE DISCLOSURE The present invention relates to a method for the qualitative and quantitative measurement, by means of microwave spectrometry, of the hydrogen isotopes, protium, deuterium and tritium, in a sample which contains hydrogen, water or a mixture thereof, and to an apparatus for imple- menting the method. Because it is a prerequisite for the use of microwave spectrometry that the isotopes be present in the form of water, and it is advantageous to have impurities in the sample in the form of active or inactive foreign mole- cules that do not interfere, the present process converts the sample into the gas and/or vapor form. The water vapor component of the sample is subjected to microwave spec- trometry and a first measured value compiled, the hydrogen component of the sample is converted to water and then subjected to microwave spectrometry and a second measured value is compiled, whereupon the two measured values are summed to provide the total isotope spectrum. Only the non- condensable gases must be removed. Processing of samples according to the method of the present invention permits the use of microwave spectrometry for the determination of the isotope spectrum in a hydrogen/water mixture.
