Ideal Column for the Separation of Neutral and Acidic Monosaccharides
The CarboPac? PA1 is an anion-exchange column for the separation
of mono-, disaccharides, and specific oligosaccharides using an isocratic
eluent. Sialic acid analysis has also been demonstrated on this column.
General-purpose column for isocratic determination of monosaccharides and
disaccharides
Detection by pulsed amperometric detection; no derivatization needed
Approved for use in a variety of official methods for the analysis of
foods
The unique MicroBead? pellicular structure of the CarboPac PA1
resin gives it stability from pH 0–14 at all concentrations of buffer salts. The
pellicular resin structure allows excellent mass transfer resulting in fast
gradient reequilibration.
The CarboPac PA1 column is used with pulsed amperometric detection; no
derivatization is required. Sensitivity on the PA1 is not as high as with the
CarboPac PA20 or PA10 for monosaccharide analysis. Thus the CarboPac PA1 is well
suited for the analysis of foods for nutritional labeling. The CarboPac PA1 has
been approved for use in a number of official methods.
