| Abstract: | Instrumentation and analytical procedures for the direct determination of lead, copper and cadmium in alcoholic beverages in the concentration range 1–100 μg 1-1 are outlined. The results are discussed with respect to detection limit, precision and time for analysis. Comparison with results obtained with atomic absorption spectrometry showed discrepancies of less than 15%. |
