This research has been carried out in a European Working Group in charge of determining the possibilities of using glow discharge mass spectrometry (GDMS) in the laboratories of the iron and steel industry. The Centre de recherches métallurgiques (CRM) has focused its activities on the analysis of pulverulent non-conducting materials. Two preparation methods specific to the analysis of non-conducting materials have been developed and validated. The first method consists in rendering conductive the samples by incorporating an element with a very low electrical resistivity (copper). The second method is based on the use of a secondary metallic cathode allowing a direct ionization of the non-conducting surface and its analysis. During the research a great number of pulverulent samples were analyzed by GDMS by using two different commercial equipment: the VG 9000 equipped with a high resolution spectrometer and the VG Glowquad equipped with a less expensive quadripole spectrometer.
