Equipment

High-resolution mass spectrometer Thermo Scientific LTQ Orbitrap XL

Equipment description

High-resolution mass spectrometer Thermo Scientific LTQ Orbitrap XL installed at the Faculty of Chemistry and Chemical Engineering is a hybrid system containing a liniar ion trap (for the acquisition of low resolution mass spectra) and a last generation Orbitrap ion trap (for acquision of high resolution mass spectra). The spectrometer has as main accesories: an Accela chromatograph, a chiller Thermoflex 900, and a nitrogen generator Parker Domnick Hunter LCMS15-1.

Characteristics

LTQ Orbitrap XL affords recording of high-resolution mass spectra and determination of exact mass of the analyzed compounds with accuracy below 3 ppm, value under the accepted limit (5 ppm) for the determination of the identity of a compund. The mass spectrometer has four ionization probes (ESI, APCI, MALDI, and nano-ESI) which allow the analysis of a wide range of compunds: organic and organometallic small molecules, supramolecular associations, peptides, proteins, polimers etc.

Apllications / Uses

  • acquisition of mass spectra of high resolution or low resolution with various ionization methods: ESI, APCI, MALDI, in both positive and negative mode
  • determination of the isotopic composition of analyzed samples
  • determination of fragmentation patterns of the analyzed compounds
  • MSn experiments
  • HPLC-MS and HPLC-MS/MS experiments
  • studies on supramolecular systems associated through non-covalent interactions
  • determinarea compoziției unor amestecuri complexe, analize calitative și cantitative
  • separation, identification and study of peptides and protein modifications
  • identification, structure determination and molecular mass distribution of polymers etc.

Opening hours

Monday – Friday: 9h00-17h00
