Sodium benzoate analysis

Sodium benzoate is often used as an antimicrobial agent to preserve food.  It is a preservative that is regulated by the US Food and Drug Administration (FDA) in the Code of Federal Regulations (21CFR Part 184.1733).  The concentration should not exceed 0.1% in food.  We have established a validated test method for the quantitative analysis of sodium benzoate by high-performance liquid chromatography (HPLC).  This will be able to tell how much sodium benzoate is in a sample to ensure that it meets the regulated limit.
