标准摘要
[中文适用范围]： ISO 14673 的这一部分| IDF 189规定了通过镉还原和光谱法测定乳和乳制品中硝酸盐和亚硝酸盐含量的方法。 该方法适用于——全脂、部分脱脂和脱脂奶粉； ——硬质、半硬质和软质奶酪； ——加工奶酪； ——乳清奶酪、酪蛋白和酪蛋白酸盐以及乳清粉。 该方法可以使用自动设备进行，特别是通过分段流动分析（SFA）或流动注射分析（FIA），从而减少实验室工作场所和废水中的镉污染。 注：这些方法分别在 ISO 14673-2|IDF 189-2 和 ISO 14673-3|IDF 189-3 中描述。 [外文原描述]： ISO 14673-1|IDF 189-1:2004 specifies a method for the determination of the nitrate and nitrite contents of milk and milk products by cadmium reduction and spectrometry. The method is applicable to: whole and partly skimmed and skimmed dried milk; hard, semi-hard and soft cheeses; processed cheese; whey cheese, caseins and caseinates and dried whey. The method may be performed using automatic equipment, in particular by segmented flow analysis (SFA) or flow injection analysis (FIA), thus reducing cadmium contamination in laboratory work places and waste water.
