Abstract

In the present mini-review, an account of the actual state-of-the-art and future possibilities offered by on-line ET-AAS is presented. Topics such as: (1) on-line analyte preconcentration (by means of precipitation, sorption, solvent extraction, and solid phase extraction); (2) analyte separation by means of chromatography, and electrochemical, microdialysis and chemical vapor generation processes; and (3) sample treatment (by microwave sample digestion, sample emulsification and dilution processes) are used to illustrate the versatility of flow injection, sequential injection analysis, stop flow and continuous flow, when coupled to a graphite furnace. The use of some of the on-line systems for speciation and the simultaneous determination of different analytes is underlined.
