Solid phase microextraction (SPME) and liquid phase microextraction (LPME) are widely used for sample enrichment and cleanup prior to an instrumental analysis. Compared to simply applicable SPME, LPME requires more manual maneuvers. In order to overcome such shortcomings of LPME, We developed in-tube microextraction (ITME). ITME uses a liquid plug inside a capillary as an acceptor phase and thus can be in-line coupled with capillary electrophoresis (CE) with ease. Since the acceptor phase is well protected inside the capillary, ITME can be carried out under severe extraction conditions. Moreover, given that the extraction and injection processes take place simultaneously, the extraction speed and efficiency are very high. Here, we present direct immersion ITME coupled with a commercial CE instrument (DI-ITME-CE) for three-phase configuration. In three-phase DI-ITME, acidic analytes in an acidic aqueous donor solution were enriched into a basic acceptor phase through athin organic layer by the driving force of pH difference.
