Applications:


The Separation of Sodium, Dioctylsulfosuccinic Acid, and Sulfosuccinic Acid
Sulfosuccininc acid and the corresponding dioctyl ester were separated on the Primesep B4 short carbon-chain anion-exchange column. Short carbon chain stationary phase allows to elute hydrophobic and acidic diester in reasonable time. No elution was observed on the mixed-mode columns with longer carbon chain analogs due to very strong hydrophobic and anion-exchange interaction.
