TCI America 9,10-Dimethoxyanthracene-2-sulfonic Acid Sodium Salt A5701

Sodium 9,10-Dimethoxyanthra cene-2-sulfonate [Fluorimetric Ion-Pair Reagent for Amines] / 9,10-Dimethoxyanthra cene-2-sulfonic 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.
