Organic acids in monoethylene glycol by ion-exclusion chromatography with inverse suppression

IC Application Note S–311 The separation of short-chain organic acids from fluoride and chloride requires diluted eluents. These weak eluents, however, induce long retention times for divalent anions. Adding a stronger eluent later in the run by use of a…
