Heavy Metal in Water Analysis


product news image

A mobile fluorescence system for heavy metal detection through surface-functionalized quantum dots

With a new analysis system that uses surface-functionalized nanocrystals as sensor material, low concentrations of heavy metals such as lead or cadmium in water can be detected directly on site.
The sensitivity depends on the heavy metal ion to be detected and is 1.9 % per µg/l for lead ions and 1.8 % per µg/l for cadmium ions. The detection limit is about 0.1 µg/l. Due to the specific surface functionalization of the nanocrystals, both a qualitative and a quantitative statement about the heavy metal content of a water sample can be made.

We present the demonstrator in cooperation with the Center for Microtechnologies (ZfM) of the Chemnitz University of Technology.
