Organic Acids

RSpak KC-811 is suitable for the analysis of organic acids. KC-811 is packed with strong cation exchange gel (bonded with sulfo groups with coordinated H⁺ as counter ion) where ion exclusion and reversed phase modes function to separate a variety of organic acids. If it is desirable that reversed phase contribute more to the separation, a reversed phase column RSpak DE-613 or DE-413 can be connected to KC-811. RSpak NN-814 is suitable for the separation of aromatic organic acids under ion exclusion and reversed phase modes.
