74598 RH I Avd for patologi DESI QTOF MS Imaging system

We intent to test a qtof mass spectrometer with a desi (Desorption Electrospray Ionization) source from Waters for lipidomics analytics of fresh frozen brain material as part of a complementary analytic process in parallel to the routine intraoperative diagnostics. Specifications: - feeding of a normal glass slide (cryoslide) as used in the department with freshly cut, frozen brain tissue (10-30µm thick)- desi source to feed evaporated tissue into mass spectrometer (exclusive rights of Waters to access Prosolias patented technique)- The procedure should work in parallel to routine diagnostics, max. 15 minutes for whole analysis including preparation.- The tissue should be used as is without any pre-treatment procedures or matrix applications. Waters is the only company that has qtof mass spectrometer with desi source for for lipidomics analytics of fresh frozen brain material as part of a complementary analytic process in parallel to the routine intraoperative diagnostics.
