的詳細介紹
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 completely resolved by cation-exchange
chromatography.
