该欧洲标准规定了用于测定蔬菜和蔬菜产品中硝酸盐含量的高效液相色谱（HPLC）和离子色谱（IC）方法。该方法适用于25mg/kg以上的样品。 硝酸根质量分数为194 mg/kg和691 mg/kg的甜菜根汁，天然污染和加标样品已被验证，硝酸盐质量分数为26 mg/kg和222 mg/kg的黑胡萝卜，含硝酸盐的冰山莴苣623mg/kg和3 542mg/kg的质量分数

This European Standard specifies a high-performance liquid chromatographic (HPLC) and an ion chromatographic (IC) method for determination of the nitrate level in vegetables and vegetable products. This method is applicable for samples with a content of 25 mg/kg or greater. It has been validated on naturally contaminated and spiked samples as beetroot juice with nitrate mass fractions of 194 mg/kg and 691 mg/kg, pureed carrots with nitrate mass fractions of 26 mg/kg and 222 mg/kg and with iceberg lettuce with nitrate mass fractions of 623 mg/kg and 3 542 mg/kg.
