The BP-100, H
+
carbohydrate column is similar to the ion exchange (850, BP-OA,
Organic Acids) column, except for a different degree of cross linking and
sulfonation. The variation in cross-linking and
sulfonation optimizes not only the separation of carbohydrates present in the
sample but also the organic acids and alcohols
which may be present. Only dilute acid is used as the mobile phase at ambient
temperatures.
The analysis of organic acids and carbohydrates in wines and fruit juices
provide information on fermentation processes
and product quality. Control of organic acid peak elution times are affected by
eluent pH and temperature; protonated
molecular species are better retained by the resin column. A dilute solvent
modifier such as acetonitrile, which can result in
an increase in back pressure, will reduce the elution time of most sample
species. This is especially true for those components
which have a high resin interaction, e.g. phthalate.
