## 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
