Analytical chemistry in controlled thermonuclear fusion

The analytical problems arising in the fuel cycle of a fusion reactor have to be discussed separately for the various subsystems of such a reactor. Thus, in the case of plasma exhaust purification, concentration assays of the tritiated impurities must be carried out quickly and, whenever possible, under flow conditions. Conventional methods may be employed for this purpose, such as mass spectrometry, FT-IR spectrometry and laser Raman spectrometry, but they will all have to be adapted to special conditions, especially for online operation.
