Nitrite and Nitrate. Nitrite and/or nitrate in foodstuffs by ion chromatography. (NMKL 165, 2000)
This method describes an ion chromatographic method for the determination of the residual nitrite and nitrate contents in different foodstuffs. The method can be applied to the analysis of meat, meat products, baby food, vegetables and cheese. The limits of detection for nitrite and nitrate ions are 1 and 10 mg/kg, respectively. The recovery of residual nitrite/nitrate varied between 96-108%.
