Abstract:
An absolute, fairly rapid method for the analysis of lithium in liquid droplets is described. It is based on the isotopic dilution of a 6Li (or 7Li)-enriched lithium salt, and on the measurement of isotopic ratios using Secondary Ion Mass Spectrometry. The sensitivity is well adapted to the analysis of lithium in minute volumes of plasma taken from patients suffering from manic-depressive psychosis.
