Resumo This paper discusses the recent development of hollow-fibre liquid-phase microextraction (HF-LPME). The principles of HF-LPME are presented with focus on both two- and three-phase extractions. Typical performance data are reported with major emphasis on recovery, enrichment, and sample clean-up, and the applicability of HF-LPME is discussed in relation to the performance data. Finally, several examples of new directions of HF-LPME are discussed to give a flavour of the future for the technique.
