Supramolecular Organic and Organometallic Chemistry Centre (SOOMCC) leaded by Prof. Cristian Silvestru and Prof. Ion Grosu brings together a group of about 40 scientists including permanent staff, post-doctorates and PhD students from the Faculty of Chemistry and Chemical Engineering, Babe\u0219-Bolyai University (BBU), Cluj-Napoca. The Center develop research in the fields of organic and organometallic synthesis, supramolecular chemistry, stereochemistry, development of organic and organometallic materials with magnetic, optical and electronical properties as well as their applications as heterogeneous catalysts or supports for metal catalysts, CO2 <\/sub>capture and storage, organic solar cells and others. SOOMCC was recognized by BBU as a Center of Excellence since 2010. \u00a0One of the major infrastructures managed within the SOOMCC is the High-Resolution Mass Spectrometer LTQ Orbitrap XL, ThermoScientific.<\/p>\n\n\n\n

High-resolution mass spectrometer LTQ Orbitrap XL installed at the Faculty of Chemistry and Chemical Engineering, BBU is a hybrid system composed of a linear ion trap (allowing the measurement of low-resolution mass spectra) and a state-of-the-art orbital ion trap (which allows measurement of high-resolution mass spectra). The main accessories of the instrument are: five ionization sources (see below), an Accela liquid chromatograph and a Parker Domnick Hunter LCMS15-1 nitrogen generator.<\/p>\n\n\n\n

The mass spectrometer LTQ Orbitrap XL allows: (a) determination of the exact mass of the analyzed compounds with an accuracy of less than 3 ppm, value below the accepted limit (5 ppm) for determining the identity of a compound; (b) recording high- or low-resolution mass spectra using five different ionization techniques i.e.<\/em> Electrospray (ESI), Atmospheric Pressure Chemical Ionization (APCI), Atmospheric Pressure Photoionization (APPI), Matrix-Assisted Laser Desorption\/Ionization (MALDI), both in positive and negative ionization modes; (c)  determination of the isotopic composition of the analyzed samples; (d)  building-up the fragmentation scheme of the analyzed compounds through MSn<\/sup> experiments; (e) HPLC-MS and HPLC-MS\/MS experiments; (f) study of supramolecular complexes and architectures; (f)  qualitative and quantitative determination  the composition of complex mixtures; (g) separation, identification and study of peptide and proteins; (h) determination of the structure and molecular mass distribution of polymers etc.<\/p>\n\n\n\n

Access policy<\/h2>\n\n\n\n

Opening hours: Monday to Friday, 9h00-17h00. No particular access conditions are required. Trained staff within the laboratory perform all experiments for the beneficiaries with or without data interpretation. Access to the infrastructure is restricted during the teaching activities and the periods of technical revision of the instrument. Students, PhD students and teaching staff from BBU have access to the experimental facility within training programs and research projects.<\/p>\n\n\n\n

Third-party access to the infrastructure is based on research contracts, co-joint publishing, exchange of experience and transfer of technology and skills programs.
