A gold amalgamator, used conventionally for Hg vapor enrichment, is reported to preconcentrate Se after hydride generation. This approach is very well compatible with atomic absorption spectrometry using a modular trap-and-atomizer device reported recently. A limit of detection for 300 s sample introduction time reached 13 pg ml-1 Se (247 pg Se absolute).
