Mass spectrometry
This service has the main mission analysis by mass spectrometry of molecules very various: organic, organometallic, inorganic, oligosaccharides, proteins, oligonucleotides, peptides, trace compounds...
The equipment available in the service of mass spectrometry is in this day of 8 mass spectrometers. These devices are complementary, they allow to satisfy most requests for analyses.
- GCT 1 Waters (mass spectrometer high resolution): EI and DCI methane direct introduction and coupling GC/MS: determination of exact masses.
- UPLC Xevo G2 Q TOF (Waters) (mass spectrometer high resolution): electrospray LC/MS and LC/MS/MS coupling and direct introduction: determination of exact masses
- Q TRAP 4500 ABSciex and U Ultimate 3000 Dionex HPLC: team of Electrospray (ESI) and Atmospheric Pressure Chemical Ionization (APCI) sources. Possibility of analyses up to m/z 2000, MS/MS (fragment, precursor ions and neutral loss), MS3, LC/MS, LC/MS/MS and determination. Very high sensitivity enhanced by on-line preconcentration.
- Q TOF 1 (Waters): source electrospray, high resolution. Project equip it with a source LIFDI.
- DSQ Thermo Fisher Scientific mass spectrometer: mass spectrometer equipped with electron impact (EI) and chemical ionization (IBD NH3) sources analysis to the 1000 low-resolution mass; ability to analyze air-sensitive compounds.
- Spectrometers Q TRAP 2000 (Applied Biosystems) and API-365 (Perkin Elmer Sciex) equipped Electrospray (ESI) and Atmospheric Pressure Chemical Ionization (APCI) sources. Possibility of analyses up to m/z 1700, MS/MS (fragment, precursor ions and neutral loss), MS3, LC/MS, LC/MS/MS and determination.
- R10-10 NERMAG mass spectrometer for analyses up to mass 2000 and with the source Fast Atom Bombardment (FAB)
