Popis: Separation of the phenylthiohydantoin (PTH) derivatives of all 20 common amino acids is accomplished in approximately 11 min with excellent resolution by using high-pressure liquid chromatography. The chromatography is achieved at 50 degrees C on an Altex reversed-phase PTH-C18 column in an ammonium acetate-buffered acetonitrile, pH 4.5, mobile phase. Simple isocratic and linear gradient steps are used. Retention times for the various PTH-amino acids are very reproducible. Because the baseline is flat and free of background noise, PTH-amino acids can be detected in the low picomole range. The simplicity of this chromatographic system allows it to be easily automated.
