The SDT650 is a combined Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) instrument capable of reaching temperatures up to 1500°C under nitrogen, air, or argon. You can look at samples up to a mass of 200mg, size and density dependent.
The RCaH hosts two pieces of equipment in Physical Sciences dedicated to thermal analysis of samples, both from Waters. The TGA 5500 which features the options of a Mass Spectrometer and autosampler, (please see the equipment page for TGA5500 for details). TGA looks at the mass change of the sample over a defined temperature range, which allows you to examine water or volatile compound retention, as well as, other aspects of the material’s thermal decomposition/volatilization or stability. DSC looks at the energy difference between heating up the sample and a known reference material. DSC is useful to look at glass transition, melting, thermal stability and many other aspects of the materials properties.
Both the TGA 5500 and the SDT 650 are controlled using the Waters Trios software, which allows for fully programable runs data analysis, the data is exportable in various formats for offline examination.
