AminoPac PA1 Amino Acid HPLC Column from Thermo Scientific

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
