标准范围

ISO 14673-1 | IDF 189-1:2004规定了通过镉还原和光谱法测定牛奶和奶制品中硝酸盐和亚硝酸盐含量的方法。本方法适用于:全脂、部分脱脂和脱脂奶粉；硬奶酪、半硬奶酪和软奶酪；加工奶酪；乳清奶酪、酪蛋白、酪蛋白酸盐和干乳清。该方法可使用自动设备，尤其是分段流动分析（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。

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.
