Trace metal analysis of Total Arsenic in water by online voltammetry
精密型 EZ系列水中總砷分析儀採用線上伏安法分析水中總砷濃度
The EZ6000 Series of Online Trace Metal Analyzers are based on the technology of stripping voltammetry, a sensitive analytical technique that can be automated for the determination of trace levels of metals in water. For many metals the EZ6000 Series boasts limits of quantification in the low ppb range, comparing the technique favorably with AAS or ICP analysis.
EZ6000系列水中微量金屬監測儀根據溶出伏安法技術，靈敏的分析技術，可達成自動化，測定水中微量金屬的含量。對於許多金屬，EZ6000系列的定量極限可達ppb級，相較於AAS或ICP方法，具有優勢。

Several product sublines with a wealth of combinations are available for determination of trace metals, including the standard single parameter and multi-parameter configurations without digestion. Measurement of complexed or adsorbed metals is possible by means of the configurations with built-in digester. Combinations of metals depend on the choice of working electrode and the priority metals for your application.
EZ6000系列提供多款監測水中微量金屬的分析儀，包括無需消解的標準單參數和多參數配置。內建消解器的配置可用於測定絡合或吸附態金屬。
