FLM was integrated in EKS to enhance online preconcentration efficiency in CE. FLM-EKS-CE was evaluated for the monitoring of paraquat and diquat in river water. SEF of up to 1866-fold compared to typical injection method was obtained. No offline sample pretreatment step was required in this new approach.
