Extraction of analytes from aqueous samples in a multiwell plate with a porous membrane at the base of each well by migration through the solvent-filled membrane pores into an acceptor phase located in each well.
Notes: - The solvent-filled filter pores function as a supported liquid membrane typically based on an organic solvent immiscible with water.
- PALME is usually performed in the three-phase mode (\(\ce{aqueous\!->\!organic\!->\!aqueous}\)).
