VDS Optigel Wine Series

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.

Optigel CH wine - This optigel phase with a particle size of 8 μm is especially suitable for the analysis of sugar and alcohol in wine, e.g. optimized in wine. Typical analytes are glucose, fructose, glycerin, ethanol.

Optigel ZAO wine is an anion exchanger phase with a particle size of 7μm and is used in wine analysis especially as a precolumn to remove interfering substances from the sample matrix when analysing sugars and alcohol. The functional group used here is quaternary ammonium with chloride as the counterion.
