Article Description

A microdialysis application for the sampling of plant pesticide residues has been developed utilizing two probes with differing perfusate rates simultaneously inserted into symmetric components of a sampling system. A simple empirical equation is proposed to calculate analyte concentrations in a semi-solid matrix using two different dialysate concentrations. In vitro application yielded excellent correlations between the calculated and spiked concentrations. Subsequent in vivo application of this technique for the determination of pesticide distributions in leaves of a jade plant (Crassula ovata) indicated the utility of this approach in complex living matrices. © 2009 The Royal Society of Chemistry.
