His research interests are trace element characterizations of different samples using Inductively Coupled Plasma-​Mass Spectrometry (ICP-​MS) and Laser Ablation-​Inductively Coupled Plasma-​Mass Spectrometry (LA-​ICP-MS). He studied transport-​processes of Laser-​induced aerosols and the improvement of detection capabilities of ICP-​Mass spectrometers for the determination of trace elements in liquid and solid samples. In the last years he worked mainly on new sample introduction systems for nanoparticles and laser-​generated aerosols and on fundamental vaporization processes of particles within an ICP. A new instrument based on a portable laser ablation system has been developed and allows direct sampling in the field, which is most interesting for archeological applications. Most recently new developments towards high spatialy resolved multielement imaging capabilities are carried out.
