Preparative GPC is generally employed to fractionate polymers, isolate components in a polymer formulation or simplify mixtures of relatively small molecules in complex matrices. 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.
- Excellent column efficiency provides optimum resolution
- High loading can isolate mg amounts for further study
- Over x10 scale up permits efficient quantification
