TCI America 1-Heptanesulfonic Acid Sodium Salt I0345

Sodium 1-Heptanesulfonate [Reagent for Ion-Pair Chromatography] / 1-Heptanesulfonic Acid Sodium Salt Ion-exchange chromatography systems have previously been utilized in HPLC analysis of ionic samples. Recently, reversed phase partition chromatography using ion-pair reagents has been developed and utilized. The ionic samples form an ion-pair with ion-pair reagents in the mobile phase to become electrically neutral. The increase in hydrophobic character of the ion-pair results in a greater affinity for the reverse stationary phase and leads to sample resolution.
