Assay of sodium monofluorophosphate for pharmaceutical use

Sodium monofluorophosphate for pharmaceutical use needs to comply with USP requirements. The actual monograph (USP 42) uses three different methods for the identification, the impurity, and the assay. Ion chromatography allows the analysis of these three parameters in one single determination. In the course of the USP monograph modernization, this ion chromatographic approach makes this type of analysis even easier.
