CarboPac PA20

by Dionex

 

The CarboPac® PA20 column line has been expanded to include a new 0.4 × 150 mm capillary column. As with all CarboPac PA 20 columns, this new capillary format provides high-resolution separations of mono- and disaccharides with no need for derivatization. The CarboPac PA20, 0.4 × 150 mm format offers the additional advantages of higher mass sensitivity, lower required sample amounts, and significantly lower solvent use.

The CarboPac PA20 is a strong anion-exchange column that provides high-resolution separations of mono- and disaccharides with no need for derivatization. This column provides baseline resolution between the six monosaccharides commonly found in mammalian glycoproteins over a wide range of eluent concentrations. The CarboPac PA20 provides slightly different selectivity from either the CarboPac PA1 or PA10, making it an attractive choice for separating difficult peak pairs.

  • The column of choice for high-sensitivity monosaccharide analyses
  • Highly efficient separations with good resolution between neighboring peaks
  • Fast analysis—less than 10 min
  • Optimized resolution of glucosamine/galactose and glucose/mannose peak pairs
  • Lower eluent consumption
  • Does not require derivatization

The CarboPac PA20 consists of 6.5 µm-diameter nonporous beads covered with a fine latex of functionalized MicroBead resin. This pellicular resin structure permits excellent mass transfer, resulting in high-resolution chromatography and rapid re-equilibration.

Similar columns from other manufacturers to CarboPac PA20

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated
Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
