The quantitative determination of 6Li and 7Li in Rhine water and determination of the isotopic distribution in some commercial Li salts have been performed by FD mass spectrometry in combination with a multi-channel analyzer. Surprisingly, the isotopic distribution in the Li salts deviates from the mean natural abundance. In contrast, the natural distribution is found in Rhine water. Using 6Li-enriched LiF as standard, 6Li and 7Li can be determined quantitatively by the method of isotopic dilution (total error 5%).
