1. A solid-phase microextraction device for measuring or identifying one or more components of interest from liquid samples arranged in a plurality of wells in a multiwell plate, said device comprising:
- a plurality of non-porous fibres, each having a distal end at least partially coated with a polymeric extraction phase for absorbing or adsorbing the component of interest from the liquid samples; and
a positioning device for guiding the coated distal end of said non-porous fibres into a submerged position within the plurality of wells of a multiwell plate, and for removing said non-porous fibres from said wells;
said positioning device comprising;
(i) a mounting plate for mounting each of a plurality of non-porous fibres in a position corresponding to a counterpart well on said multiwell plate, the non-porous fibres being retractably mounted within the mounting plate; and
(ii) a guide for moving said mounting plate so the coated distal end of each of said non-porous fibres is submerged in a well of the multiwell plate, for retracting said non-porous fibres from said wells, and for positioning said non-porous fibres into a multiwell plate containing desorption solvent or into an analytical instrument.

23. A solid-phase microextraction device for measuring or identifying one or more components of interest from liquid samples arranged in a plurality of wells in a multiwell plate, said device comprising:
-
a plurality of non-porous fibres, each having a distal end at least partially coated with a polymeric extraction phase for absorbing or adsorbing the component of interest from the liquid samples, said extraction phase being formed as a thin flat membrane in the shape of a fin on the distal end of the non-porous fibres; and a positioning device for guiding the coated distal end of said non-porous fibres into a submerged position within the plurality of wells of a multiwell plate, and for removing said non-porous fibres from said wells; said positioning device comprising; (i) a mounting plate for mounting each of a plurality of non-porous fibres in a position corresponding to a counterpart well on said multiwell plate, the non-porous fibres being retractably mounted within the mounting plate; and (ii) a guide for moving said mounting plate so the coated distal end of each of said non-porous fibres is submerged in a well of the multiwell plate, for retracting said non-porous fibres from said wells, and for positioning said non-porous fibres into a multiwell plate containing desorption solvent or into an analytical instrument. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
