Abstract

An often applied technique for tritium accountancy involves pressure, volume, temperature, concentration (PVT-c) measurements. The analytical glovebox system (AGS) serving the concentration measurements consists of an Omegatron mass spectrometer and a gas chromatograph. The calibration programme for both instruments is presented and the results are discussed. The calibration includes the species likely to be found as impurities during the normal operation of the laboratory. The parameter influence for the different components of the single instruments (such as variations of the magnetic field, trimer formation) is analysed and its consequences for the final results are evaluated.
