摘要：

Four types of plastic with four different nominal Cd concentrations in the range of 40 to 400 mg/kg were sampled, homogenized and certified at CBNM on behalf of VDA (Verband der Automobilindustrie). The homogeneity control of these materials was performed using solid sampling graphite furnace Zeeman atomic absorption spectrometry. On each of the four materials 60 analyses were carried out on micro samples (60 to 250 mug per analysis, depending on the Cd content) taken from 60 different wire cuts. Homogeneity assessments and determination of the minimum sample mass are made and discussed.
