Abstract

By incorporating a new electrochemical detector based on potential gradient detection, a portable capillary electrophoresis (CE) instrument for field analysis has been developed. The portable CE instrument can be used for detecting a board range of ionizable species in aqueous solutions. The detection limits of the instrument for most ions were around 0.1 ppm with a linear range of three orders of magnitude. Ions in mineral water (K⁺, Na⁺, Ca²⁺, Mg²⁺, Cl^-, NO₃^-, SO₄^2-, CO₃^2-) and bromate in drinking water were analyzed as examples with the portable capillary electrophoresis instrument.
