Overview

Pressure versus Linear Velocity

Pressure vs. linear velocity for 1 M NaCl on Macro-Prep 25 S in a 1.6 cm (ID) x 12.5 cm (L) column.

Macro-Prep 25 S Resin is a strong cation exchange resin that offers high-resolution separations at high flow rates with medium pressures. It possesses the same rigid, macroporous, and hydrophilic properties of 50 µm Macro-Prep High S support but in a 25 µm bead that offers higher resolution.

Features and Benefits of Macro-Prep 25 S Resin

  • Benchtop to pilot-scale separations, where maximum sample recovery and purity are important
  • Fewer chromatographic steps required
  • Removal of protein variants and other difficult contaminants that would require additional validation if present in the final formulation
