Hermetic Thermal Gravimetric Analyser - Mettler Toledo TGA/DSC 3+

The Thermal Gravimetric Analyser (later also “TGA”) measures the change in mass of a sample as it is heated, cooled or held at a constant temperature in a defined atmosphere. Samples that are sensitive to air can be prepared and analysed under a hermetic process at a reduced pressure thus preventing their decomposition. The intended use of the TGA is for the analysis of stable solid-state materials, their synthesis studies and analysis of ALD precursors. Volatility and thermal stability are essential properties of ALD precursors. They are inherently very air sensitive, implying fully inert handling. Fully inert TGA at reduced pressure provides direct access to the key parameters of ALD precursors developed at CHEM, allowing swift feedback to our precursor development. Solid-state research focuses on the behavior of multi-metal oxides – such as battery materials – or their precursors. The Department of Chemistry and Materials Sciences has developed solid knowledge of TGA use and analysis, but we lack a device fulfilling our teaching and research needs. An automated sample loader with hermetic sample crucibles ensures consistency and minimizes errors in multi-user environment.
