On Applicability of a Miniaturised Laser Ablation Time of Flight Mass Spectrometer for Trace Elements Measurements
Figure 4
The temporal variation of ion yields of individual isotopic mass peaks recorded after each 1000 laser pulses (a). (b) displays a cumulative sum obtained by accumulation of individual ion yields and reflect the rate of ion yield increase during the measurements. The cumulative sums of the ion yields of the individual isotopic components of elements and clusters normalised to the cumulative sum of the ion yield of 54Fe are displayed in (c).
