摘要：

Ion-pair and ion-exchange chromatography were used for the separation of model substances like metal-EDTA and metal-peptide complexes. Real samples like food extracts and human serum were separated by size-exclusion chromatography. The HLPC/ICP coupling was simply realized by connecting the column outlet of the chromatographic system with the nebulizer of the element specific detection systems ICP-OES and ICP-MS, respectively. In food extracts a correlation was found between zinc and sulfur as well as between copper and phosphorus; all measured metals were exclusively present in the 10-14 kD range. Copper in the 68 kD region was found to be correlated with sulfur in serum.
