Thermal Analysis Coupled with GC-MS and FT-IR
Thermal analysis is a standard physical characterization technique which can be applied in almost any sample, such as solid, semi-solid, or liquid. IMSERC's instrumentation covers three major thermal analysis methods, i.e., Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and Differential Thermal Analysis (DTA) where mass, enthalpy, and temperature difference can be measured as a function of temperature, respectively. TGA can be measured simultaneously with either DSC or DTA that allows various thermal events to be monitored, such as glass transitions, melting, crystallization, decomposition, evaporation, sublimation, oxidation, and reduction.
Additionally, our simultaneous thermal analysis (STA) instrument can be coupled with a Gas Chromatography-Mass spectrometer which enables the separation and identification of any volatile species coming off the sample. Furthermore, the STA furnace can be coupled with a Fourier-transform infrared spectrometer (simultaneously with the GC-MS unit) for additional characterization capabilities. With the combination of various spectrometers and TGA, each weight loss event in a complex TG trace can be assigned to specific molecules escaping the sample. Please check out some selected publications resulted by IMSERC users along with the list of other physical characterization services available in IMSERC.
