Abstract

It has been found that hydrophilic ions, such as protonated tris(hydroxymethyl)aminomethane (H+THMAM), are eminently suitable as counterion for reversed-phase partition high performance liquid chromatography. The anionic metal chelates with 2,2′-dihydroxyazobenzene were separated on C18-bonded silica packing with an aqueous methanol mobile phase (pH 7.9) containing THMAM, and detected spectro-photometrically.
