These preparative columns is ideal to fractionate polymers, isolate components in a polymer formulation or simplify mixtures of relatively small molecules in complex matrices.

• Excellent column efficiency provides optimum resolution
• High loading can isolate milli grams amounts for further study
• Over 10 times scale up permits efficient quantification

It is packed with the same rigid, high performance media as the analytical columns so that mixtures of materials are easily separated on the basis of size, preferably in a low boiling organic solvent. They are then collected as a series of discrete fractions and isolated by simple evaporation of the solvent.
