On Applicability of a Miniaturised Laser Ablation Time of Flight Mass Spectrometer for Trace Elements Measurements

Figure 1

Schematic overview of the laser ablation mass spectrometer used in this study. The instrument is of cylindrical symmetry, 120 mm long and its diameter is 50 mm. The laser beam enters from the top and is focussed on the sample placed on XYZ translational stages at the bottom. Positive ions leaving an ablation plume enter the interior of the analyser through the nose-piece electrode for mass analysis (see text for details).
