High-pressure liquid chromatographic determination of saccharin in artificial sweeteners and pharmaceuticals.

A high-pressure liquid chromatographic procedure is presented for determining saccharin in various formulations. The method is fast, precise, and accurate and is specific for saccharin in the presence of its most likely impurities and degradation products. Reversed-phase chromatography on a micro-C18 column is utilized with an internal standard, and detection is by UV absorption at 280 nm.
