Abstract
The reversed-phase liquid chromatographic retention behavior of poly(l -tryptophan)s and poly(d,l-tryptophan)s) whose molecular weight ranged from 5.4 kD to 37.25 kD is examined using a C-8 chemically bonded sta tionary phase and binary mobile phases of tetrahydrofuran (THF)-water and ternary mobile phases of THF-water-methanol. The retention ofpoly( l-tryptophan)s is compared with that of poly(d,l-tryptophan)s. Linear- Solvent-Strength (LSS) model is examined in describing the retention b ehavior. The effect of adding a third solvent to the binary mobile pha se is also discussed.
