Polymethacrylate-based reversed phase columns are available in a range of pore and particle sizes. Although often not as efficient and less robust than silica-based RPC columns, key advantages of polymer-based columns are:

Wider pH range (1 to 12) allows many basic compounds to be analyzed in their uncharged form, thus reducing secondary adsorption and improving peakshape.

Improved recovery for peptides and proteins due to reduced secondary interactions.

 Highlights
  • Polymer-based RPC columns are chemically stable from pH 2-12, allowing operation at basic pH where silica-based columns have limited chemical stability.
  • Polymer-based TSKgel RPC columns can be cleaned and endotoxin removed by using either strong acid or base.
  • Polymer-based TSKgel RPC columns are available packed with nonporous resins (NPR) or with porous resins of various sizes. The proper column to use is selected based on sample MW or application.
