Liquid-phase microextraction of analytes from a liquid (or gaseous) sample by a supported liquid membrane in the form of a porous hollow fibre with solvent-filled pores. The analytes are transferred to an acceptor phase contained in the cavity of the hollow fibre.
Notes:
- A typical experimental arrangement is shown in the figure below.
- The supported liquid membrane is generally an organic solvent immiscible with water and the sample an aqueous solution.
- The acceptor phase can be aqueous, which provides a three-phase extraction system (\(\ce{aqueous\!->\!organic\!->\!aqueous}\)), or an organic solvent, providing a two-phase extraction system (\(\ce{aqueous\!->\!organic}\)).
- The sample is agitated or stirred during extraction.
