HPLC Analysis of Amino Acids

Dionex offers two approaches to amino acid analysis: (1) anion-exchange separation by AAA-Direct in which amino acids are detected directly, without the need for derivatization, or (2) anion-exchange separation with postcolumn derivatization. The AminoPac^® PA10 is the recommended column for AAA-Direct, whereas the AminoPac PA1 is used with postcolumn derivatization.

• Amino Pac PA10 columns to separate free amino acids without the need for derivatization
• Amino Pac PA1 columns to separate free amino acids with derivatization
• Compatible with solvent, high pH, and high temperatures.
• Provides easy scale-up.

AminoPac columns are used for high-resolution separations of free amino acids as well as for separation and detection of a wide range of sugars, phosphorylated amino acids, and common oxidation products of sulfur-containing amino acids.
