LFEC-2006Lead（pb）and Cadmium（cd）Analyzer
Introduction
The metal ions to be analyzed are pre-oxidized on the working electrode at a constant potential slightly more negative than their peak potential for a specified duration to achieve their enrichment. Subsequently, the potential is scanned from negative to positive values, causing the species enriched on the electrode to be oxidized and dissolved; the oxidation peak is then recorded. The composition of the analyte is determined based on this oxidation potential, and its concentration is determined based on the peak height.
Reagent Preparation:
The original factory provides a set of matching reagents, which can be used for 3 months if it is used 8 times a day.
The application, procurement, storage, and use of reagent raw materials must comply with the requirements of applicable laws and regulations!
