美國TraceDetect?
美國TraceDetect（微檢）公司以化學傳感器的微處理技術而著稱，目前是世界上最專業的重金屬分析儀表制造商。公司具有Nano-Band（納米帶）電極專利技術并研制出系列重金屬分析儀，可對水樣中的金屬含量快速測定，靈敏度為全球最高，可達ppt級。
TraceDetect, a Seattle-based company, was formed in 1998 to research and commercialize new chemical and optical sensors through reductions in electrode size made possible by microfabrication techniques. To that end, the Nano-Band? electrode was developed for trace metals analysis, and specific software was designed to support several products. At present, the commercialization of automated trace metals measurements instrumentation, using stripping voltammetry and the Nano-Band electrode are the primary foci of the company
