Abstract

Mass spectrometric isotope dilution analysis (MS-IDA), one of the few absolute methods in the field of microanalysis, is here considered in the case of lead determination. This because of the importance of the element and because of the variety of problems associated with lead measurement due to its widespread presence in the environment which makes difficult the determination at trace levels if suitable precautions are not taken during the sampling and the analytical cycle. The paper after a description of the principles of the MS-IDA technique and of the sample preparation for lead analysis considers the critical parameters connected with the method and the influence of contamination on the value of the isotopic ratio. Finally results of measurements carried out under routine conditions on blood samples with a wide range of concentration are reported and a comparison with atomic absorption results is given.
