The design and operation of the LASMA instrument, which combines laser ablation with time-of-flight mass analysis, is described. This study aims to evaluate the LASMA technique for the semi-quantitative analysis of multielement metal samples and non-conducting powder mixtures of known composition. The methodology involves utilizing a Q-switched Nd-YAG laser and a reflectron time-of-flight mass spectrometer to acquire mass spectra up to 250 amu. Results indicate that the LASMA technique demonstrates a detection limit of approximately 50 mg/g, suggesting its efficacy for elemental bulk analysis. The compact design of the LASMA instrument is highlighted as a significant advantage, making it particularly suitable for in situ studies outside of laboratory environments, thereby broadening its application scope. Despite advances, the mechanisms of laser ablation remain only partially understood, necessitating further investigation. Overall, this work not only details the LASMA operation but also underscores its practical applications in various analytical settings.
