On-line pre-concentration of atrazine by antibody immobilization capillary electrophoresis Original Research Article

Antibody coupled capillary electrophoresis was employed in the pre-concentration and detection of atrazine at the parts per billion (ppb) level. A 1000-fold increase in detection has been demonstrated in the use of IgG anti-atrazine monoclonal antibodies for the analysis of atrazine in well water by capillary zone electrophoresis (CZE) with UV–VIS detection. These results were confirmed by an enzyme linked immunosorbent assay (ELISA) specific for atrazine.
