✦ Synopsis

Abstract

CE suffers from an inherent low concentration sensitivity. Analyte detection limits can be improved by combining CE with SPE. This paper presents an overview of coupled SPE‐CE systems that have been reported in literature. Attention is paid to fundamental aspects of coupling SPE and CE, as well as to important SPE requirements. Interfaces for inline and online coupling with CE are critically discussed, and their mode of operation is outlined. Advantages and limitations of the interfaces are discussed and typical examples are selected. Finally, some future developments are discussed.

## Abstract Automatic SPE has been coupled on‐line to CE by a transfer tube and the replenishment system of the CE instrument. The approach allows the target analytes (__viz.__ creatinine, creatine, xanthine, hypoxanthine, uric acid, __p__‐aminohippuric acid and ascorbic acid in urine samples) to b
