Low temp. GC coupled online with ICP-MS was used to identify volatile metal and metalloid compds. in gases and condensates from a domestic waste deposit. Seven Sn species could be identified by external std. addn. and further volatile compds. of Sn, Bi, Hg, As, Sb, and Te could be found by b.p. calibration. Some tech. and methodical concepts towards quantification of the results are indicated.
