Heavy metals in the environment pose major health threats and, thus, are of great interest to researchers globally. Additionally, substances such as endocrine disruptors, volatile organic compounds, platinum group metal salts, and other environmental toxins pose health and safety risks to the public.

The need to detect these materials has driven considerable research to develop sensors for environmental monitoring. Screen printed electrodes offer an alternative to larger, more stationary methods of detection by offering low detection limits, fast response times, small size, and in situ analysis, while only requiring very low volumes.

Metrohm DropSens offers an array of screen printed and interdigitated electrodes. Not only can you custom design a new electrode, but modifications can also be made to existing electrodes. See below for some examples of common electrodes and modifications for environmental applications.
