Waters Corp., Milford, Mass., introduced the Rapid Evaporative Ionization Mass Spectrometry (REIMS) Research System with iKnife sampling, combining direct-from-sample ionization with high-performance time-of-flight mass spectrometry and intuitive analytics. The system eliminates the need for sample preparation and chromatographic separation, providing food researchers with near-instantaneous data acquisition.
In REIMS, direct, rapid heating of the samples leads to the formation of vapor that is rich in sample-specific chemical information. The vapor is taken directly into the mass spectrometer (XevoG2-XS QTof or SYNAPTG2-Si HDMS) where the molecules are analyzed by time-of-flight mass spectrometry. The
