Determination of nitrate and bromide in foodstuffs by high-performance liquid chromatography

Abstract

The determination of nitrate and bromide directly from aqueous extracts by high-performance liquid chromatography on an amino phase chemically bonded to silica gel is described. In comparison to other methods, this procedure needs less clean-up, no derivatization and is faster. The detection limit varies between 0.05 ppm and 10 ppm depending on the food matrix. © 1980.
