Sweeteners in Soft Drinks

Shown below is an example of the high-performance liquid chromatography (HPLC) analysis of the sweeteners aspartame and saccharine, benzoic acid, sorbic acid, and glycyrrhetinic acid in soft drinks. The soft drink was directly injected and analyzed.

Analysis of Sweeteners in Soft Drinks

High-Performance Liquid Chromatograph

High-Performance Liquid Chromatograph

A high-performance liquid chromatograph (HPLC) measures the content of various components in a sample. A liquid medium flows through the HPLC flow channel. When a sample is introduced into the instrument, the components of the sample are separated in a column and the amount of each component is measured by a detector. HPLC can handle a much wider range of target samples and components than GC, including difficult-to-vaporize and heat-sensitive components.
