The objective of this study is to develop an automatic separation technique of ultra-trace multi-elements. The experimental conditions of sequential separation with a single anion-exchange column were optimized. An automatic separation system was assembled. A reference environmental sample was separated and quantitatively analyzed with the optimized system, and the features of this system were evaluated. The elements of interest were sequentially and completely separated within 6 hours. The chemical recovery yield was more than 95%. This evaluation suggests that a sample in more than 500 micro grams (equivalent to several micro meters in diameter) of sample can be analyzed.
