Abstract:

A method is described by which samples containing as little as 5 ng of lead can be isotopically analyzed. The procedure was developed for use with lubricating oils containing additives labeled with particular lead isotopes, but it can also be applied to the determination of lead in other materials. It consists of three steps 1 digestion of the organic sample to release the lead into aqueous solution, 2 anodic deposition of the lead onto platinum electrodes, and 3 secondary ion mass spectrometry. Quantitative determination of the amount of lead in a sample can be accomplished by adding to the sample a known amount of a standard lead compound with an isotopic composition different from the sample.
