Product Introduction

Water Heavy Metal (Metal Ion) Rapid Detection System MAS-G1

I'd like a quote.

In response to the need for real-time detection of heavy metals in water quality testing, Ruizhun Technology's portable water quality analyzer MAS G1 uses electrochemical technology to not only reduce laboratory instruments to a handheld size, but also retain its advantages of speed, sensitivity and accuracy. One device has multiple parameters and the measurement items can be changed at will. It is convenient to carry and measure anywhere. It is a good helper for on-site rapid determination of hot spots, enterprise internal control, environmental auditing, field investigation and other usage scenarios.

Electrochemical analysis began with the polarography developed by Czech chemist Jaroslav Heyrovsky in 1920. By the mid-1960s, the improvement and refinement of the classical voltammetry method laid the foundation for the electrochemical analysis system that is still widely used today. The three-electrode system (working electrode, reference electrode, auxiliary electrode) is an essential element for the implementation of electrochemical detection method, among which the working electrode is the most important. Starting from the early polarography using the dropping mercury electrode (DME), the rotating disk electrode (RDI) used to study various analytical dynamics, various materials (such as gold, platinum, carbon, silver) and different types of electrodes (such as microelectrodes, ring disk electrodes), the creation and change of each working electrode is to better meet the needs of experiments and research.

Although electrochemical analysis technology cannot determine multiple heavy metals in a single sample, its analysis device has been miniaturized to a size that can be operated on the palm of your hand due to the vigorous development of the precision motor industry. It has the advantage of being developed into an on-site detection tool while being easy to operate and low in price [1,2]. The four common electrochemical methods used for metal detection are cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV) and differential plus voltammetry (DPV). LSV, SWV and DPV are often combined with the anodic stripping method to improve the analytical sensitivity, and are abbreviated as ASV (Anodic Stripping Voltammetry), SWSV (Square-Wave Stripping Voltammetry) and DPSV (Differential Pulse Stripping Voltammetry) respectively.
