说明

一般說明

方法：试纸条和试剂比色法，0.02 - 0.05 - 0.1 - 0.2 - 0.5 mg/L As, 0.1 - 0.5 - 1.0 - 1.7 - 3.0 mg/L As, MQuant^®

砷试纸条适用于测定水、药品、制备的生物标本和液体食品中的砷。在此MQuant^®砷试纸中，试纸条需与其他试剂结合使用。通过添加锌粉（一种固体酸）和一种用于消除干扰性硫化物离子的氧化剂，可以从样品中释放出砷。在试纸的反应区上，会形成黄棕色染色。通过目视比较试纸条的反应区与比色卡的各色块，可半定量测定三价砷（III）和四价砷（V）浓度。试纸非常适合经济、快速地预测样品，以便在使用定量方法（例如Spectroquant^®试纸）前估算砷浓度和可能的稀释度。
