Abstract

The Analytical Glovebox System (AGS) in ETHEL (European Tritium Handling Experimental Laboratory) consists of two analytical methods: mass spectrometry and gas chromatography. The system serves, together with the results from the pressure, volume and temperature (PVT) technique, for controlling the purity of the tritium in the store. The mass spectrometer is an Omegatron with a permanent magnet. The gas chromatograph contains a specially prepared Ca-Na-mordenite packed column, a cryostat to programme the desired operating temperature, a thermal conductivity detector and an ionization chamber detector. Both systems are set up from single components and in this configuration are not commercially available.

The AGS was initially tested with different hydrogen isotopes mixtures (cold commissioning) before the operation with tritium. In anticipation of the hot commissioning of the laboratory (prove nucleari) the AGS has been calibrated with gas mixtures containing tritium, deuterium, protium, helium-3 and argon. The results from the calibration process (qualitative and quantitative analysis) are discussed. The different mass spectra and chromatograms are presented and evaluated for different operating parameters. .
