Use of simultaneous dual-probemicrodialysis for the determination of pesticide residues in a jade plant (Crassula ovata)

摘要

A microdialysis application for the sampling of plant pesticide residues has been developed utilizingntwo probes with differing perfusate rates simultaneously inserted into symmetric components ofna sampling system. A simple empirical equation is proposed to calculate analyte concentrations inna semi-solid matrix using two different dialysate concentrations. In vitro application yielded excellentncorrelations between the calculated and spiked concentrations. Subsequent in vivo application of thisntechnique for the determination of pesticide distributions in leaves of a jade plant (Crassula ovata)nindicated the utility of this approach in complex living matrices.
