The Mass spectrometry platform available in Babes-Bolyai University offers the possibility of analysis and characterization for organic, organometallic compounds, supramolecular associations, peptides, proteins, polymers, including complex mixture from biological samples. The HRMS infrastructure affords the recording of high-resolution mass spectra and the determination of exact molecular weight of the analysed compounds with accuracy below 3 ppm. The mass spectrometers have specific software and databases as well as the necessary auxiliar instrumentations for Sample Separation to provide the best resolution, sensitivity, and selectivity. The platform also includes an ICPMS spectrometer that has been designated to deliver rapid and precise isotope ratio and quantitative analysis of trace elements in solid and liquid matrices.
