Time of flight-mass spectroscopy (TOF-MS), ultraviolet (UV) absorption and Raman spectroscopy, and quantum chemistry calculations were used to investigate the thiourea dioxide (TDO) structure in aqueous solution. TOF-MS with the direct injection sample method was used to get molecular weight ...
The acquired data was corrected for time-skew and, the coincidence events were energy filtered, only those coincidences falling within a ± 30% of the photopeak value were considered for CTR calculations. Then, the coincidence photon arrival time were histogram for each ROI and fitted using...
Synthesis of Cubic PtPd Nanocrystals: In a typical synthesis of cubic PtPd nanocrystals, sodium tetrachloropalladate (Na2PdCl4, 20 mM, ie. 0.67 mL, 1.0 mL or 1.33 mL), potassium tetrachloroplatinate (K2PtCl4, 20 mM, ie. 1.33 mL, 1.0 mL or 0.67 mL), sodium iodide (NaI, 75....
different reaction time were analyzed by GC-MS. Turn-Over-Frequency (TOF) Calculations (a) General concept 1. TOF of the catalyst = (mole of nitrobenzene conversion ) / (mole of surface atoms of catalyst × reaction time) 5 2. Since both Pd and Pt have a face-centered-cubic ...
Spraying aniline (93 amu) on the prism surface and using 2 ns UV laser pulses, mass resolutions of 3,900 and 11,000 have been achieved in a linear TOF-MS and in a reflectron TOF-MS, respectively. Theoretical calculations indicate that mass resolution of over one million is possible, if...
Because such calculations are time consuming the ability of the MS data to reduce the number of species that need to be considered is significant. A number of features appear to be common to many frames across the CID dataset. Several aspects of these data that we find interesting can be ...

Molecular analysis by parallel tandem mass spectrometry (MS/MS) imaging contributes to the in situ characterization of biosynthetic intermediates which is crucial for deciphering the metabolic pathways in living organisms. We report the first use of TOF-
