Process Development


The MiniChrom TOYOPEARL DEAE-650M column is a small, pre-packed column (8 mm ID × 10 cm) with 5 mL resin volume designed for fast method development or resin screening. MiniChrom columns guarantee optimal performance and can be connected to common high or medium pressure liquid chromatography systems.

MiniChrom columns are packed by Atoll GmbH. They are reproducibly and individually flow-packed to account for the varying compressibility of each resin. Therefore, each column provides an accurate representation of resin performance that translates to full scale production columns.
