摘要
我国环境监测中测定氨氮的国标方法为纳氏试剂分光光度法、水杨酸分光光度法、蒸馏—滴定法和电极法。SK—100型实验室氨氮自动分析仪采用纳氏比色原理,用冷光源和窄带干涉滤光技术以及单片机数字处理技术,不仅实现了样品分析的自动化,同时能保证数据的准确性,可广泛应用于地表水和工业废水的监测。
SK-100 laboratory automated ammonia-nitrogen analyzer is based on the Nessler＇s colorimetic principle. The instrument uses a cold light source,narrow band interference filter and single chip computer digital processing technology.It can perform automated sample analysis with high accuracy,and could be widely used in monitoring surface water and industrial wastewater.
