Mass spectrometry imaging with high resolution in mass and space [PDF]

Histochemistry and Cell Biology, 2013
Mass spectrometry (MS) imaging links molecular information and the spatial distribution of analytes within a sample. In contrast to most histochemical techniques, mass spectrometry imaging can differentiate molecular modifications and does not require labeling of targeted compounds. We have recently introduced the first mass spectrometry imaging method

High Resolution Mass Spectrometry of Polyfluorinated Polyether-Based Formulation [PDF]

Journal of the American Society for Mass Spectrometry, 2015
High resolution mass spectrometry (HRMS) was successfully applied to elucidate the structure of a polyfluorinated polyether (PFPE)-based formulation. The mass spectrum generated from direct injection into the MS was examined by identifying the different repeating units manually and with the aid of an instrument data processor.
