Determination of Lithium by FD Spectra Accumulation

The determination of the isotopic distribution of the metals presented in this contribution is a facile analytical procedure because 

These results dearly demonstrate that FDMS, in conjunction with a multichannel analyzer, represents a powerful method for the trace analysis of metals. Obviously, the unavoidable statistical fluctuations in the FD ion currents have lost then-detrimental effect on the FD assay and the signal-to-noise ratio of the signals in question has been improved considerably by spectra accumulation. In addition, it can be expected that by use of the isotope dilution technique quantitative determinations of high sensitivity and accuracy can be accomplished without prior treatment of the original biological or environnmntal sample.
