This paper presents a low-capacity cation-exchange chromatography method for the analysis of UV-absorbing dipeptides and amino acids. A newly marketed low-capacity cation-exchange column packed with sulfo-functionalized highly cross-linked macroreticular poly(ethylstyrene-divinylbenzene) copolymer was used for the simultaneous determination of imidazole amino acids, aromatic amino acids, and creatinine...
A simple and versatile cation-exchange chromatography technique for the simultaneous determination of urinary creatinine (Cre), creatine (Crn), methionine (Met), tyrosine (Tyr), phenylalanine (Phe), histidine (His), and tryptophan (Trp) was developed. A novel low-capacity cation-exchange column packed with a newly developed sulfoacylated hypercross-linked macroreticular polystyrene-divinylbenzene...
