Abstract
The resolution of a 15-component mixture of phenylthiohydantoin (PTH) amino acids using metal ion impregnated silica gel plates is reported. The spots are located by exposing the chromatograms to an iodine chamber. The method provides a rapid, simple, and less expensive chromatographic system, provides resolution for certain difficult combinations, and leaves the PTH amino acids unaltered chemically.
