Journal ArticleDOI
Development of a simple in-vial liquid-phase microextraction device for drug analysis compatible with capillary gas chromatography, capillary electrophoresis and high-performance liquid chromatography.
TL;DR: A simple, inexpensive and disposable device for liquid-phase microextraction (LPME) is presented for use in combination with capillary gas chromatography, capillary electrophoresis (CE) and high-performance liquid chromatography (HPLC).
Journal ArticleDOI
Electrokinetic migration of acidic drugs across a supported liquid membrane.
TL;DR: Initial data supported that electrokinetic cross membrane extraction provided repeatable data and linear response between original donor concentration and final acceptor concentration of the acidic model compounds.
Journal ArticleDOI
Electrokinetic migration across artificial liquid membranes: Tuning the membrane chemistry to different types of drug substances
TL;DR: Twenty different basic drugs were electrokinetically extracted across a thin artificial organic liquid membrane with a 300 V d.c. electrical potential difference as the driving force, resulting in permeation of the interface.
Journal ArticleDOI
Simulation of flux during electro-membrane extraction based on the Nernst-Planck equation.
TL;DR: The model demonstrated that the magnitude of the electrical potential difference, the ion balance of the system, and the absolute temperature influenced the flux of analyte across the SLM, and high ionic concentration in the acceptor solution relative to the sample solution was advantageous for high flux.
Journal ArticleDOI
Bioanalysis of drugs by liquid-phase microextraction coupled to separation techniques.
TL;DR: Hollow fibre-based liquid-phase microextraction based on disposable hollow fibres may provide high enrichment of drugs and excellent sample clean-up, and probably has a broad application potential within the area of drug analysis.
