Our Setaram TG-DSC 111 achieves simultaneous DSC (variation in the heat flow) and TGA (variation in mass) measurement on a catalyst sample. It is built based on a symmetrical arrangement, which is especially attractive for thermogravimetric measurements, with drift compensation during heating (buoyancy effect) and measurement of very small variations in mass (less than 1 µg).

The TG-DSC111 capabilities include:

  • Temperature range: from -120 up to 830°C
  • Coupling of a microbalance with a Calvet-type DSC
  • Varied and controlled atmospheres: 
    • Inert gases
    • Reactive gases (O2, H2, CO,…)
    • Corrosive gases 
    • Vacuum
  • Coupling with a gas analyzer (MS or GC) 
  • Possibility of using the DSC or TG alone

    • Catalysis studies include:

  • In-situ calcination
  • Steady-state reaction
  • Gas adsorption/desorption
  • Temperature programmed
           -reaction
           -decomposition
           -phase change
           -deposition
           -reduction

    The products released during an in-situ calcination (in He) of a Copper-Zinc-Zirconia precursor are graphed together with the derivative of the weight change with respect to temperature.
