Column-switching linked to large sample volumes to preconcentrate beta-blockers at trace levels in environmental water
This paper describes about an automated on-line enrichment method for the simultaneous determination of seven beta-blockers in river water using a short liquid chromatography column for preconcentration coupled with LC-DAD. The method performs the preconcentration of 30mL of river water samples (5%...
