一般描述

Mquant®铵测试（原MColortest®）可检测诸如地下水和地表水、海水、饮用水和水族馆用水中的铵离子。铵氮(NH4-N)部分以铵离子形态存在，部分为氨形态。两种形态之间存在pH依赖性平衡。

分析方法
在强碱溶液中，氮可与氯化试剂反应形成一氯胺。该产物又会与百里酚反应生成蓝色的吲哚酚衍生物。由于空白试剂本身显黄色，测试液显黄绿色至绿色。通过目视比较测量溶液的颜色与色卡的色场，可以半定量地测量氨离子浓度。独特的光辉光环和精细的颜色分级可实现精确的分析，即使在浓度范围的低端也是如此。使用补充包1.18455，原始测试套件可以使用很长时间，使其成为一个特别经济的生态系统。 

本试验适用于以下环境中氨的测定
  • 地下水和地表水
  • 饮用水和矿泉水
  • 水族馆水、水产养殖水
  • 锅炉及锅炉给水、冷却水
  • 流程水
  • 废水
  • 电镀废水
  • 游泳池水
  • 施肥营养液
  • 经过适当样品预处理的食品

此测试不适用于海水。
