Thermo gravimetric analysis (TGA-MS) measures mass loss from materials as a function of temperature and gas-phase atmosphere (i.e., to evaluate material stability). Mass and volume measurement of materials using air-displacement method, via TGA-MS, determines density and porosity of materials. Differential scanning calorimetry (DSC) determines phase changes and measures the heat capacity of the various materials used in HTE (important for the modeling and design for planar cells and stacks). BET for measuring surface area and porosity. NMR provides quantitative information on chemical functionality present in a sample. Secondary ion mass spectrometry (SIMS) and nano-SIMS provide surface composition analysis. Auger electron spectroscopy provides high resolution spatially resolved chemical composition images enabling rapid analysis of chemical composition. Electron probe micro analysis determines chemical composition and redox state. FTIR (transmission, ATR, and in situ DRIFTS) and Raman spectroscopy provide chemical speciation information. Mössbauer spectroscopy provides information about valence state, coordination number, and magnetic ordering temperatures.
