What is Low-Noise Potentiostat for Heavy Metal Detection about?

This document presents a low-noise portable potentiostat circuit designed for the electrochemical detection of heavy metals such as arsenic, mercury, and copper at ppb levels. The proposed system operates without the need for external devices or software, achieving a noise floor of 1.6 nV/Hz at 10 kHz, and demonstrates reliable performance in on-site measurements. The circuit utilizes a gold-coated electrode and is validated against a commercial potentiostat, enabling simultaneous detection of multiple cont
