Chemical Analytics

The service group Chemical Analytics offers a broad range of analytical services in the fields of chromatography, mass spectrometry and atomic spectrometry for the research departments of INM, for groups of the university of Saarland and external costumers. In addition to the identification and quantification of your analytes, we optimize established methods according to your requirements and develop special analytical solutions to your specifications. Our analytical equipment includes instrumental methods like Gas Chromatography-Mass Spectrometry (GC/MS), Liquid chromatography (HPLC) with different detectors (RID, DAD and ESI-MS). Atomic spectrometric methods like Atomic Absorption Spectrometry (AAS) with Flame (FAAS) and Graphite Furnace (GFAAS) Atomisation, Optical Emission Spectrometry with Inductively Coupled Plasma (ICP OES) and CHNOS analyses are also available. Our new High-Resolution Sector-Field ICP-MS quantifies analytes down to the lower ppt-range and the determination of isotope ratios and Single Particle analysis are also possible.
