一般說明
该方法类似于EPA 354.1、APHA 4500-NO2- B和DIN EN 26 77。
该Spectroquant®硝酸盐比色池测试可以准确定量水样中的硝酸盐。硝酸盐是动植物生长所需的必需营养素。但是,硝酸盐水平升高可能会危害健康,特别是对怀孕妇女和婴儿而言。因此,许多国家都对水源中的硝酸盐水平进行了监管。
方法原理:在酸性溶液中,硝酸盐离子与磺胺酸反应形成重氮盐,它与N-(1-萘基)-乙二胺二盐酸盐反应形成可用光度法测定的紫红色偶氮染料。
该Spectroquant®试剂测试盒包含高度稳定的即用型试剂混合物,用于根据随附说明书所述流程进行分析。
我们所有的比色池和试剂测试盒都配备了独特的实时ID(2维码),可实现无缝方法识别,并包含相关必要信息,例如批号、有效期和自动校准更新。
