## Abstract We present a new system for the sensitive analysis of cephalosporins by CE using both on‐line SPE and large‐volume sample stacking (LVSS). Sample volumes of 250 μL were loaded onto the SPE microcolumn which was then desorbed with 426 nL of ACN. The SPE elution plug was injected into the
## Abstract SPE coupled in‐line to CE, as the strategy to enhance the concentration sensitivity in CE, has been used to enrich naproxen in tap water samples. In this study, a microcartridge containing an octadecyl silica (C~18~) sorbent was placed near the inlet within the separation capillary colu
