A new trimethylamine amination polychloromethyl styrene nanolatex ( TMAPL ) and TMAPL coated capillary column (ccc‐ TMAPL ) were successfully prepared. The TMAPL coating was characterized with reversed steady EOF values of ca. ‒16.8 × 10 −5 cm 2 V −1 s −1 . It was applied to establish open‐tubular ( OT ) CEC and field‐amplified sample stacking ( FASS ) OT ‐ CEC methods for the determination of bromate in tap water. Compared to OT ‐ CEC , the LOD with FASS ‐ OT ‐ CEC was improved from 80 to 8 ng/mL. The developed FASS ‐ OT ‐ CEC method was practically used for the analysis of bromate in tap water samples with recoveries ranging from 93.6 to 103.5%.
