Thermal Analysis by Thermogravimetric Analysis (TGA/DSC) coupled with FTIR

Brand: Mettler Toledo, Thermo Scientific

Model: TGA/DSC1, Nicolet iS10 and Nicolet iZ10

​Thermogravimetric Analysis (TGA) is used to study the response of different materials while exposed to variable temperature and gas environment. Temperatures up to 1100 °C can be reached. Reaction gasses that can be applied are inert (N2, Ar,..) and oxidizing gasses (Air, O2,..) as well as diluted hydrogen (4% H2 in for example Argon). Properties such as mass change and relatively large enthalpy changes can be measured. TGA instruments in our possession are actually Simultaneous Thermal Analysis (STA) instruments capable of measuring both TGA as well as Differential Scanning Calorimetry (DSC) signal. However the STA instruments are 50x less sensitive than dedicated DSC instruments. Installed autosampler equipped with automatic pan lid removal and automatic pan piercing accelerates measurement of multiple samples (turntable can accommodate up to 34 sample pans). Line connecting the TGA to FT-IR can be heated to 225 °C and the IR-cell to temperature of 300 °C. FT-IR is equipped with a KBr Beamsplitter and a DTGS detector capable to acquire IR spectra between 400 – 4000 cm-1.
