Twenty Years of Knudsen Effusion Mass Spectrometry: Studies Performed in the Period 1990-2010

Investigations carried out by Knudsen effusion mass spectrometry on metals, alloys, oxides, and fullerene systems in the period 1990-2010 are reviewed in the present paper. 362 original papers were published in this period by ca. 45 research groups thereby showing still large activity in this unique area. The fundamentals and recent developments of the method are briefly reported. Data to the systems studied, temperature ranges, vapour species identified in the equilibrium vapours and thermodynamic properties obtained in the study are reported. Important features of these studies are briefly discussed as well.
