Using magnetite/silica/poly(methacrylic acid‐co‐ethylene glycol dimethacrylate) (Fe3O4/SiO2/poly(MAA‐co‐EDMA)) magnetic microspheres, a rapid and high‐throughput magnetic solid‐phase extraction coupled with capillary zone electrophoresis (MSPE‐CZE) method was developed for the determination of illegal drugs (ketamine, amphetamines, opiates, and metabolites). The MSPE of target analytes could be completed...
A method based on poly (methacrylic acid‐co‐ethylene glycol dimethacrylate) monolith microextraction and octadecylphosphonic acid‐modified zirconia‐coated CEC followed by field‐enhanced sample injection preconcentration technique was proposed for sensitive CE‐UV analysis of six antidepressants (doxepin, clozapine, imipramine, paroxetine, fluoxetine and chlorimipramine) in human plasma and urine. A...
