Homogeneity determination of Cd in plastic CRMs using solid sampling absorption spectrometry
Four types of plastic with four different nominal Cd concentrations in the range 40 to 400 mg/kg were sampled, homogenised and certified at CBNM on behalf of VDA (Verein 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 micro-g per analysis, depending on the Cd content) taken from 60 different wire cuts. Homogeneity assessments and determination of the minimum sample mass were made and are discussed.
