Treatment in Time-resolved Mass Spectrometry

The main goal of data treatment in conventional mass spectrometry (MS) is to facilitate identification and quantification of analytes. The focus of time-resolved mass spectrometry (TRMS) is to track variations of identities and quantities of analytes and products over time. In many chemical reactions, the concentrations of reactants decrease and those of products increase with time. In more complex reactions, reaction intermediates exist and their concentrations may increase and decrease within certain periods of time. The evolution of reaction intermediates is distinct from that of reactants and products. TRMS provides an insight into the progress of reactions by identifying molecules based on their mass-to-charge (m/z) ratios. It also determines concentrations of molecules based on signal intensities of ions. Thus, it is important for TRMS to interpret MS data on highly complex and dynamic systems correctly. This chapter will first introduce definitions of various technical terms, and then discuss how to predict molecular compositions of complex mixtures based on the information contained in mass spectra.

During these temperature and gas treatments, processes like reduction, oxidation and sintering take place. In Chapter 2 it is clarified what processes are responsible for the final metal particle size and particle size distribution. This is done using a combination time resolved extended X-ray absorption fine structure spectroscopy (quick EXAFS) and mass spectrometry. [Pg.7]
