The User Guide/Instructions for Use (IFU) for Product 1.14739 states explicitly that "this test is not suited for seawater". This is likely due to the presence of interfering substances such as Magnesium ions (Mg2+) in the seawater. Consider Product 1.14657, which is a somewhat less sensitive colorimetric assay called Ammonium Test in freshwater and seawater.

一般描述
该方法符合ISO 23695标准,该标准规范了对这种重要参数使用“小规模密封管方法”。该方法还类似于EPA 350.1、APHA 4500-NH3 F、ISO 7150-1和DIN 38406-5。
该Spectroquant® Ammonium Cell Test可对废水、地下水、地表水和海水中的铵态氮进行无氰定量分析。通常,铵盐会从施肥的农业地区的径流进入水源,而铵盐含量升高是粪便污染的重要指标。
其他应用领域是食品&饮料(例如乳清)以及环境和农业样品(例如土壤)的分析。
Spectroquant®测试预装试剂随附预装的16 mm圆形比色皿以及所有必要的试剂,可根据提供的说明书中进行分析。
所有Spectroquant® 反应池和试剂测试套件都配备了独特的实时ID,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。
