In this paper the use of phenylalanine as eluent for indirect photometric chromatography is reported. The effects of the mobile phase pH, phenylalanine concentration etc. on the eluent strength and the sensitivity of detection are discussed. Using 3 mM aqueous solution of phenylalanine at pH 3.0 containing 1% methanol as the mobile phase, a mixture of alkali metals was separated and sodium ion concentration in water was determined on a low-capacity cation-exchange column.
