该欧洲标准规定了一种离子交换色谱法，用于测定硝酸盐含量为50 mg/kg至300 mg/kg的硝酸盐和硝酸盐含量为硝酸根离子，亚硝酸盐含量为40 mg/kg左右的肉制品的硝酸盐和亚硝酸盐含量为亚硝酸根离子注意:从实验室间研究获得的验证数据表明，该方法也可以应用于蔬菜和婴儿食品中硝酸盐的测定，参见（1），（2）。此外，该方法可以应用于亚硝酸盐含量大于40mg/kg的肉制品中亚硝酸盐的测定

This European Prestandard specifies an ion-exchange chromatographic method for the determination of the nitrate and nitrite contents of meat products having a nitrate content of 50 mg/kg to 300 mg/kg as nitrate ions and a nitrite content of approximately 40 mg/kg as nitrite ion. Note: Validation data obtained from interlaboratory studies show that this method may also be applied to the determination of nitrate in vegetables and baby food, see (1), (2). Furthermore, the method may be applied for the determination of nitrite in meat products having a nitrite content of greater than 40 mg/kg.
