The analytes leave the furnace in the gas stream, or are entrained by a carrier gas. The analytes in the gas stream may be collected in an absorbing solution, on a carbon or other filter or by condensation on a cool surface. In the case of mercury this can also be done by amalgamation with a noble metal. The analytes may then be swept and released from the trap, by heating, into a sampling source for analysis.","contexts":[],"links":[{"term":"carrier gas","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/C00863"},{"term":"filter","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/F02384"},{"term":"test sample","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/T06285"}],"sources":["PAC, 1988, 60, 1461.
