☆100% Divinylbenzene Packing for Durability and Performance 

☆Change Solvents without Damaging the Column

☆Operate at High Temperatures or Pressures 

☆Replace Several Conventional Columns with one Jordi Column 

☆Choose from Multiple Surface Chemistries to Solve Your Polymer Analysis Problems

Jordi is the only company that makes GPC packings from 100% Polydivinylbenzene (DVB) for compatibility with high temperatures, high pressures and the widest range of solvents. Competitors make their packings from fragile polystyrene- divinylbenzene copolymers, (PS-DVB). Changes in solvent, temperature and pressure cause shrinkage and swelling to a greater degree in their columns.

Figure 1: GPC Durability Test - Here is a dramatic example of Jordi GPC column durability. Initial chromatograms were obtained using THF as mobile phase. Each column was then stressed by a sudden change of mobile phase from THF to methanol. Methanol was run through each column for approximately 16 hours, at which time the mobile phase was changed back to THF.
