EZ6000 Trace heavy metal analyzer

Measuring principle:

The Hach EZ6000 trace metals analyzer uses anodic stripping voltammetry (ASV), a sensitive and reliable electrochemical analysis method based on the current-voltage curve during oxidation at the electrode surface. This method involves the enrichment and stripping of metal ions at the electrode surface, and a selective oxidation reaction occurs at this electrode during the stripping phase. All steps of the analysis process, including sampling, sample transport, cleaning, and data exchange, are controlled via an industrial-grade PC panel.

Instrument features:

• The Hach EZ6000 trace metals analyzer is an anodic stripping voltammetry (ASV) heavy metal detector with a sensitive electrochemical analysis method, excellent performance, and simple operation

• This heavy metal detector has a built-in sample digestion unit for treating water samples containing complex metal substances or water samples with high organic content

• Controlled and communicated via an industrial panel computer, with up to eight-channel analysis

• This trace metals analyzer features automatic calibration and automatic cleaning, and the electronic gas components are fully separated from the wet section of the instrument for convenient maintenance

• Features expanded data communication and exchange functions

• Compared with other heavy metal detectors, the EZ6000 trace metals analyzer consumes less sample and reagent

• Excellent correlation with standard laboratory methods
