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

Figure 7

Isotopic pattern of Fe, Mo, and Pb elements and their oxides and clusters. Bar spectra of oxides and clusters represent isotopic pattern calculated from natural isotopic distribution of accompanying elements. The isotopic abundances of elements are usually reproduced with 1% accuracy whereas the isotopomers of oxides and clusters can be measured generally within 2% of the calculated value.
