摘要：

The phenylthiohydantoins (Pth) of the common amino acids can be resolved in a single analysis using a 25 × 0.46-cm DuPont Zorbax cyanopropylsilane (CN) column developed with a gradient of methanol/acetonitrile (17:3) in sodium acetate buffer, pH 5.4. The Zorbax CN columns exhibit greater durability, reproducibility, and sensitivity than do columns with an octadecylsilane (C18) support when used for Pth amino acid analysis in automated polypeptide sequencing. © 1979.
