  • Title: Blood lead determination by flameless atomic absorption spectroscopy.
    Author: Nise G, Vesterberg O.
    Journal: Clin Chim Acta; 1978 Mar 01; 84(1-2):129-36. PubMed ID: 639296.
    Abstract:
    A simple procedure for flameless atomic absorption analysis of lead in blood is described. It is based on the use of a temperature-controlled heating unit, which, with a photodiode, measures and, by electronic feedback, controls the temperature of the carbon rod. Examination of the influence of various heating has been made. Blood samples with heparin were diluted with Triton X-100, HNO3 added, and 2 microliter of the mixture analysed. Automatic background correction was used. Signals were evaluated by an electronic facility which gives integrated as well as peak height values. The method appears to be accurate and reproducible. The C.V. was, on average, 4%.
