3 PULSED ELECTROCHEMICAL DETECTION IN ION CHROMATOGRAPHY William R. 1 INTRODUCTION The first commercial electrochemical detector (EC) for high performance liquid chromatography (HPLC) was introduced in 1974, and over the past several decades its popularity, breadth, and application have grown significantly. The reasons for its success can be directly attributed to its high sensitivity, often high selectivity, and wide linear range. Also, EC detectors are fairly simple in construction, relatively inexpensive, and rugged.

H2 SO4 ), the electrolyte is present chiefly in the interstitial liquid, while the occluded phase tends to retain its pure water form. Because of the high concentration of negative charge and consequent high negative electrostatic potential at the outer surface of the resin bead, the presence of a pore is essential for analyte retention because it represents a zone with significantly lower electrostatic repulsion than the outer surface of the bead. A cloud of analyte molecules carrying the same charge polarity as the functional groups on the resin can therefore move between the interstitial eluent and the occluded eluent in the pores, providing a basic retention process.
