Bruker ApexQe FT-ICR Instrument

The installation of the instrument started end of 2006 and all specification were met in June 2007. The Collaborative Research Center (Sonderforschungsbereich 623) "Molecular Catalysts: Structure and Functional Design" established by the German National Science Foundation (DFG) within the Heidelberg Faculty of Chemistry and Earth Sciences in 2002 was is continued until 2009. This second period of SFB 623 also provided funding of this FT-ICR mass spectrometer.

The ApexQe is a hybrid instrument comprising a mass selective quadrupole, a RF-only hexapole cell for ion storage or collision-induced dissociation and an Infinity ICR cell. There, IRMPD, ECD and SORI-CID experiments can be performed for structure analysis of ions.
It is equipped with a cryocooled 9.4 T superconducting magnet and an Apollo II MTP ion source which can be switched from ESI to MALDI operation almost instantaneously. In 2013, we were able to add a DART source to this instrument, which is put to frequent use ever since.
