A simplified and effective phase separator for use in flow systems is described. The sample, 300 l, is introduced into an aqueous stream (flow injection). The aqueous phase, containing the sample plugs, is divided into small segments by an organic phase using a commercial T-connector. Separation of

A modified phase separator incorporating a supported teflon membrane is described. The separator has very high phase-separation efficiency even under extreme conditions of phase-volume ratio and total flow rate. The use of an appropriate support is shown to give much better endurance to the membrane
## Abstract In this study, two microextraction methods, __viz.__ continuous‐flow microextraction (CFME) and static liquid‐phase microextraction (s‐LPME), were optimized and compared for the determination of __p__‐toluidine in water and __Chlamydomonas reinhardtii__ samples. The calibration curve fo
