ICP-MS

Instrumentelle Analytik (Umwelt- und Bodenchemie)

Model:
NexIon 1000 (Perkin Elmer) with FAST System
Description:
During the last decades inductively coupled plasma mass spectrometry (ICP-MS) became the most common analytical device in trace element and inorganic nanoparticles detection. It offers very low detection limits and hence enables us to measure from some parts per billion (ppt or e.g. ng/L) level detecting several elements in the same run (multi element detection). Furthermore, the single particle plugin enables us to determine the size and the concentration of metal containing nanoparticles in complex matrices. Additionally, ICP-MS coupled to other analytical devices (e.g. high pressure liquid chromatography (HPLC)) delivers a high versatility in element speciation and size separation.

At the moment in the working group environmental and soil chemistry ICP-MS is used to deal with the following environmental topics:
 

  • Detection of trace contaminants in environmental matrices (e.g. arsenic and cadmium in soils, surface and ground waters, sediments, sludge, plants and invertebrates)

  • Behavior and fate of metal(loid)oxid and metal(loid) nano particles in the environment (INTERNANO)

  • Analytical support in ecotoxicity tests
