FT-ICR spectrometry (experimental rooms E9 and E10)

FT-ICR spectrometry (E10)
Mass spectrometry with the Esquire (E9)
E4
  • The first instrument in this room is a Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometer based on a 7 tesla magnet (Apex Qe, Bruker). This instrument features an ElectroSpray and a Nanospray ionization sources. The most important characteristic of this mass spectrometer is the so-called “Qh interface”, which is placed in between the source and the ICR cell: Q stands for Quadrupole, allowing for mass-selection, and “h” for hexapole in which mass-selected ions can be accumulated and collisionally cooled (through multiple collisions with Ar) prior their transfer into the ICR cell.
  • The second instrument in this room is an Optical Parametric Oscillator/Amplifier (OPO/OPA) laser system delivering nano-pulses at 25 Hz (YAG pump). This laser system from Laservision is tunable in the 2000-4000 cm-1 spectral range. An additional stage can be added at the exit of the OPA, where DFG using a AgGaSe2 crystal allows for tuning the 650-1800 cm-1 spectral range.
