Oxalic Acid

Although oxalic acid cannot be separated from chloride (from NaCl) under normal eluent conditions, the quantification of oxalic acid is made possible by using 50mM perchloric acid as an eluent using RSpak KC-811. Under such conditions, oxalic acid should be detected by RI or UV (at 210nm) detector.
