ABSciex QSTAR ESI-QTOF MS (2009/2009)

General Information

TOF mass spectrometer. Qstar Elite is a high resolution hybrid quadrupole Time-of-Flight (TOF) mass spectrometer for accurate mass definition and structural characterization. The device enables the characterization of large molecules (including proteins, metal clusters). It is also able to determine the fragmentation of ions in the gas phase of the compounds by using the collision-induced dissociation (CID) measurements.

Korkean erotuskyvyn sähkösumutusionisaatio hybridimassaspektrometri tarkan massan määrittämiseen  ja rakennetutkimukseen. Mahdollisuus analysoida myös kookkaita yhdisteitä (ml. proteiinit, metalliklusterit)  sekä tutkia  yhdisteiden kaasufaasin rakennetta törmäysaktivointimittausten (CID) avulla.
