AN209: Determination of Fluoride in Acidulated Phosphate Topical Solutions Using Reagent-Free Ion Chromatography

Instrument Type: IC

The success of water fluoridation in preventing and controlling dental caries has led to the development of many fluoride- containing products. The determination of fluoride is critical to ensure that the labeled amount of fluoride is within specifications for quality control. Here, we describe an approach for determining fluoride using a Reagent-Free IC system with IonPac AS18 column in less than 15 min. This approach eliminates the need to manually prepare eluents and thereby increases the automation, ease-of-use, and reproducibility between analysts and laboratories.
