Kurzbeschreibung
The BOKU Core Facility Mass Spectrometry (CFMS) provides high-end separation science and mass spectrometry for proteomics, glycomics, metabolomics as well as elemental and isotopic analysis in life, environmental and food sciences.
The CFMS equipment and services enables research and applications in several “-omics” fields at one location. Nano-LC-MS/MS is used for studies requiring proteomics and glycoproteomics data, while LC-MS/MS, GC-MS/MS, and high-resolution molecular mass spectrometry platforms are applied to the analysis of small molecules using targeted (quantitative) and non-targeted approaches. The non-targeted approaches allow differential analysis, mass spectrometric fingerprinting and compound discovery using advanced identity confirmation workflows.
In addition to the molecular mass spectrometric platforms, the CFMS contains three ICP-MS systems situated in a clean room. Two systems are used for quantitative analysis, and one multi-collector system for isotope ratio analysis.
Besides providing instruments, we offer professional training of entire analytical workflows, comprising experimental design, sampling, sample preparation, analysis, and data evaluation. Moreover, we offer analytical services for all described methods and applications.

Research Services
Proteomics and glycomics
In the fields of proteomics and glycomics, we provide electrospray time-of-flight and ion trap mass spectrometers with different tuning configurations as well as various source options to address a broad variety of research questions. The combination of on-line liquid chromatography as a separation technique allows for in-depth identification and quantification of complex sample mixtures. The analysis of glycosylated peptides as well as free glycans and many other post translational modifications is one of our core competences.
Small molecules
We provide LC and GC separations in combination with triple quadrupole mass spectrometry systems for quantification of a broad range of small organic molecules covering a wide base of applications. One of our specializations is metabolomics for biotechnology applications. In this context we provide technology and methods delivering high quality data for cellular metabolism studies.
Our high-resolution time of flight instruments allow non-targeted analysis and support identity confirmation and screening workflows using accurate mass, ion mobility, and fragmentation-supported workflows. Methods covering a range of sample types and research questions can be developed upon request.
Elemental and isotope ratio analysis
We provide sector-field and quadrupole-based ICP-MS systems for quantification of almost all elements of the periodic system in various matrices. An additional focus lies on elemental speciation analysis, i.e. the on-line combination of separation techniques (LC, GC, CE) with ICP-MS for investigation of elemental species and element/biomolecule interaction. In this context we provide technologies delivering information of metal/protein stoichiometry or binding efficiency.
Methoden & Expertise zur Forschungsinfrastruktur
With the Core Facility Mass Spectrometry (CF MS), the BOKU (at the VIBT) offers internal and external users a state-of-the-art equipment pool for performing analyzes in the field of isotope, element and molecular mass spectrometry. Measurements are carried out both by the employees of the CF MS and, after appropriate training, by the users themselves. The CF MS has laboratories for sample preparation, an ICP-MS clean room laboratory and several measuring stations with LC-MS and GC-MS-based large devices.
The CF MS is looked after by experienced staff. These have a high level of competence in the field of sample preparation, chromatography and mass spectrometry and also a broad knowledge in the field of bio, food and environmental sciences. These synergies ensure that the current and future requirements of the BOKU scientists and the scientific community as a whole can be met efficiently and with the highest quality standards.
The excellent equipment of the CF MS enables the development of appropriate methods and their application in the routine. The broad portfolio of methods ranges from targeted absolute and relative quantification using molecular and elemental mass spectrometry and the determination of stable isotope ratios using multi-collector ICP-MS to the possibility of non-targeted analysis using high-resolution mass spectrometry for proteomics, glycomics and metabolomics. The CF MS receives scientific support from the Institute for Analytical Chemistry and the Institute for Biochemistry at the BOKU Department of Chemistry.
