“…The extraction coil should be several metres long to allow sufficient time for the extraction to take place. Usually a nonpolar material is selected for the extraction coil, because an organic solvent forms a film on the inner wall of a nonpolar coil, maximising the contact area between the two phases [66]. The recoveries can be improved by increasing the amount of extraction solvent.…”

This review provides an overview of the approaches available in order to perform on-line coupling of various extraction techniques with liquid and gas chromatography, for the analysis of semivolatile and nonvolatile analytes in liquid and solid samples. The main focus is on the instrumental set-up of these techniques. Selected real applications are described by way of illustration. The extraction methods suitable for on-line coupling covered in this review are: liquid-liquid extraction, solid-phase extraction, membrane-based techniques, pressurised liquid extraction, supercritical fluid extraction, and microwave- and sonication-assisted extractions. The following systems are not covered in this review: on-line coupled solid-phase extraction-liquid chromatography, purge-and-trap-GC, and membrane extraction with a sorbent interface-GC.

“…+3 and HNO 3 It was found that when 300 l of 100 g ml −1 solution of iodide was injected into the carrier stream, the peak height was increased with increasing Fe +3 concentration up to 30% (W/V). Further increase in Fe +3 concentration did not affect the peak height.…”

“…[7][8][9][10][11][12][13][14][15] Another approach, exploited in some commercial systems, is to use porous, planar membranes that are selectively permeated by one of the two phases. [16][17][18][19][20][21] In previous work 4, 6,22 we reported an alternative method for separating immiscible liquids, using a commercially sourced porous polytetrafluoroethylene (PTFE) capillary, see Fig. 1a.…”
