汞是环境污染调查、食品卫生检验中的重点元素。关于汞的分析方法和测量装置的研究在我国已经取得了很大的进展。但是,目前国内广泛使用的各类测汞仪一般都要经过化学前处理,分析流程长,步骤繁琐,甚至会造成较大的测量误差。 KT—81型测汞仪采用加热分解,塞曼效应原子吸收方法,是一种新型测汞仪。它 Mercury is a key element in environmental pollution investigation and food hygiene inspection. Research on mercury analysis methods and measuring devices has made great strides in our country. However, at present, various types of mercury-measuring instruments widely used in China generally undergo chemical pre-treatment, the analysis process is long, and the steps are cumbersome, which may even cause large measurement errors. KT-81-type mercury analyzer using thermal decomposition, Zeeman effect atomic absorption method, is a new mercury analyzer. it
