Rapid and sensitive UHPLC screening of additives in carbonated beverages with a robust organic acid column

The analysis of food additives in carbonated beverages is important as many additives are controlled as part of the formulations of these beverages. In addition, analysis may detect possible counterfeiting of branded products. Being able to identify and quantify food additives in beverages quickly and with high sensitivity is therefore important.

This application demonstrates the following:
• The capability of the Acclaim OA column and Vanquish Flex Binary UHPLC system in combination to give rapid separation of food additives in carbonated beverage with excellent linearity, reproducibility, and recoveries.
• The capability of the Vanquish Flex Binary system to provide excellent retention time precision through its injection control and binary pump proportioning with innovative mixing units.
