Abstract: Bulk analysis of ceramics and other non-conducting materials with a laser ionisation mass spectrometer offers the advantage of minimum sample treatment and shortanalysis time. Such an instrument can be constructed by coupling a laser to the ion source of a double focussing mass spectrometer. In this report the conversion of a spark-source MAT-SM1B instrument to a laser-ionisation mass spectrometer will be described, with special emphasis on sample handling, ion optics and improvement of ion transmission. The results of measurements on various samples clearly demonstrate that nearly any material can be analysed qualitatively. Due to the poor reproducibility of the ionisation condition quantification will only be possible in favourable cases. Using a Nd/YAG laser with a high repetiton rate (700 Hz) and recording the spectra on photoplates a detection limit of 80 ppm(w) was measured.
