Thanks to electrochemistry development, ACCUSENSING MAS-G1 is not only performed as hand-held size but also remains the accuracy and sensitivity of lab. instrument. By replacing smart chip, MAS-G1 can switch over to different analyte mode to achieve multi-parameters analysis in one device. Owing to its portability and ease of operation, MAS-G1 is an ideal tool for hot-spot identify, factory internal control, environmental audit and field investigation.

ELECTROCHEMISTRY KNOWLEDGE BRIEF SHARING
The field of electrochemical analysis was initiated by Czech chemist Jaroslav Heyrovsky in 1920 with the development of polarography. By the mid-1960s, significant advancements in classical voltammetry laid the foundation for the widespread and continued use of electrochemical analysis systems. The three-electrode system (comprising a working electrode, a reference electrode, and an auxiliary electrode) is crucial for implementing electrochemical detection methods, with the working electrode holding particular importance. Various types of working electrodes have evolved over time, starting from the early use of the Dropping Mercury Electrode (DME) in polarography, to rotating disk electrodes for studying the kinetics of different analytes, and the development of diverse materials (such as gold, platinum, carbon, and silver) and electrode types (including microelectrodes and ring-disk electrodes), each designed to better suit the experimental and research needs.
While electrochemical analysis techniques may not allow for the simultaneous determination of multiple heavy metals in a single sample, advancements in precision engineering have led to the miniaturization of analysis devices to handheld sizes. These devices offer the advantage of being potentially developed into on-site detection tools due to their ease of operation and affordability [1,2]. Commonly used electrochemical methods for metal detection include Cyclic Voltammetry (CV), Linear Sweep Voltammetry (LSV), Square Wave Voltammetry (SWV), and Differential Pulse Voltammetry (DPV). LSV, SWV, and DPV are often combined with the Anodic Stripping Method (ASV) to enhance analytical sensitivity, abbreviated as ASV (Anodic Stripping Voltammetry), SWSV (Square-Wave Stripping Voltammetry), and DPSV (Differential Pulse Stripping Voltammetry), respectively.
