Detection of Multiple Heavy Metals 1/5- Introduction

For many lab technicians, quantitative analysis is an everyday task. Monitoring processes, product quality, etc. are common tasks for electrochemical analysis. With raising awareness of pollution, monitoring heavy metals in water reservoirs, pipes, rivers, etc. is getting more and more important. Heavy metals are very suitable for electrochemical detection and even very low concentrations can be measured. Quantification limits in the range of parts per trillion (ppt) have been demonstrated.

Cyclic Voltammetry 1/4- Introduction

Moving from passive potentiometric experiments to potentiostatic experiments by controlling the potential was an important development. However, the step that followed towards potentiodynamic experiments may have been even more important for modern electrochemistry. Potentiodynamic experiments made it easy to collect all the data needed for a plot of current I versus potential E. These plots are called a voltammogram and the technique used for measuring is called voltammetry. In a short period of time the cyclic voltammetry (CV) provides a lot of information and allows kinetic investigations. It is by far the most used technique by PalmSens customers. Experienced electrochemists read quite some information from the shape of a CV.
