Abstract
Methylenediphosphonic (MDP) acid has been analyzed by reversed-phase ion-pairing high pressure liquid chromatography. MDP was ion-paired with tri-n-octylamine in the mobile phase and was chromatographed using a reversed-phase octadecylsilane column. The MDP ion-pair was detected, upon elution from the column, by a retractive index detector.Keywords
