Polymer Phases made by VDS optilab

Under the name Optigel, VDS optilab offers various ion-exchange separation phases on a polymer basis. The matrix used here is a polystyrene-divinylbenzene network, which is modified in accordance with the desired function.

This makes it possible, in contrast to silica gel phases, to be able to work over a very wide pH range without destroying the phase itself. However, when using polymer phases, care must be taken that these are not subjected to a pressure higher than 100 bar.

The Optigel polymer phases can be used in the following separation problems:

  • carbohydrates
  • organic acids
  • alcohols
  • sugar alcohols
  • wine analysis
  • and many more…

For a detailed overview, see the following table.
