TOPIC VIII "Ultra HR-MS"

European Network for FT-ICR mass spectrometry

The European Network of Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometry centres involves ten different universities and research institutes and three industrial partners. The project  is funded as Horizon 2020 infrastructure program and starts in 2018 for a period of four years. Methodological expertise relating to the FT-ICR technology will be developed and related services and scientific exchange are offered for scientist in Europe and worldwide.

Here in Rostock we will focus on the development and application of “non-common ionization techniques” (e.g. photoionization) and coupling systems of gas chromatography and  thermal analysis to high resolution mass spectrometry.

Development and application of photionization techniques for aerosol analysis

Air pollution is one of the most critical risk factors for environmentally caused diseases. To trace the chemical factors involved , new methods for the chemical characterisation of primary and secondary aerosols are needed. Especially, polyaromatic hydrocarbons and numerous carbonyls exhibit acute toxic/mutagenic effects and require sensitive methods for detection.

Due to the complex chemical composition of aerosols, high resolution mass spectrometry is the ideal technique for their chemical characterisation. In this project, combustion generated aerosols and corresponding aged aerosols are sampled within the framework of the “New HICE Project” and are investigated on molecular level by hyphenating photoionization to ultra high mass spectrometry.

High resolution mass spectrometry for petroleum samples

The ultra-high resolution mass spectrometric instrumentation installed at the University of Rostock will be deployed for the analysis of complex petroleum samples. In particular, so-called “troublemakers” in up- and down-stream processing of crude oil, such as Asphaltenes and Resins, as well as sample material of enhanced oil recovery (EOR) investigations will be in focus.

For this purpose primarily thermal analysis and gas chromatography hyphenated to atmospheric pressure ionisation techniques, such as atmospheric pressure chemical ionisation (APCI), atmospheric pressure photo ionisation (APPI) and atmospheric pressure laser ionisation (APLI), will be utilised. Selected dissociation techniques delivers additional structural information. One important aspect will be combining these results with data from other FT-MS based measurements, e.g. laser desorption or electrospray ionisation. Additional other mass spectrometric approaches, e.g. single photon and resonance enhanced multi photon ionisation (SPI/REMPI) and spectroscopic techniques like NMR will be applied to provide a more detailed description of the chemical space.
