AminoPac PA1 Amino Acid Column
For Specialized Amino Acid Applications with Postcolumn Derivatization
The AminoPac? PA1 column is a high-speed, pellicular, strong, anion-exchange column. The PA1 delivers high-efficiency separations as a result of its nonporous-core particle. Its strong anion-exchange characteristics are imparted by agglomerating surface MicroBead? particles that are functionalized with the quaternary ammonium functional group, resulting in a higher capacity than typically offered by nonporous resins.
- Resolves phosphorylated and other amino acids by anion-exchange chromatography
- Separates acid-labile amino acids under basic pH conditions
- Separates strongly acidic amino acids
- Requires OPA or ninhydrin postcolumn derivatization
The anion-exchange selectivity of the AminoPac PA1 can be used to resolve peaks that cannot be resolved using a cation-exchange column. For example, O-phosphorylated amino acids are resolved and eluted near the end of a hydrolysate chromatogram. Arogenic acid, a precursor to tyrosine and phenylalanine, decomposes under the acidic conditions required for cation-exchange separation or PITC derivatization, but it is stable in alkaline eluents used with AminoPac PA1 column.
The PA1 is particularly well suited for acidic and acid-labile amino acids and for amino acid pairs not compley resolved by cation-exchange chromatography.
