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

Figure 5

Part of two mass spectra obtained at different laser irradiances. The spectrum in (a) shows an increase of the detection efficiency for C and B elements. The mass peak broadening observed in (a) is attributed to space charge effects resulting from the increased ion abundances.
