Online Sample Preconcentration in Capillary Electrophoresis using Analyte Focusing by Micelle Collapse
journal contribution
posted on 2023-05-16, 23:09 authored by Joselito Quirino, Paul HaddadPaul HaddadA dimension for online sample preconcentration in capillary electrophoresis (CE) without modification of current CE commercial instrumentation is introduced. The focusing mechanism is based on the transport, release, and accumulation of molecules bound to micelle carriers that are made to collapse into a liquid phase zone. More than 2 orders of magnitude improvement in detection sensitivity for model steroidal compounds using sodium dodecyl sulfate micelles as carrier is demonstrated.
