Thermal Analysis
Equipment
The Institute’s capabilities to support thermal analysis enables quantitative analysis of how the mass of material changes over time as temperature changes and analysis of gases emitted from the material during the heating cycle.
Analysis
A suite of instruments is available offering quantitative analysis:
- Thermogravimetric Analysis (TGA)
- Simultaneous Thermal Analyser (STA)
- Differential Scanning Calorimetry (DSC)
- Differential Thermal Analysis (DTA)
- Quadrupole Mass Spectrometer (QMS)
Features, Applications and Capability
- Thermogravimetric analysis (TGA) quantifies the amount of moisture, low order carbon (coal char), high order carbon (coke), soot and ash in samples of blast furnace dust and sludge.
- Simultaneous thermal analysis (STA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. It heats from ambient up to 2400°C with combined thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) or differential thermal analysis (DTA). Heating rates are between 0.001 to 50°C/min. Balance system offers sample loads up to 35g and measurement range (35g) with 0.1 µg resolution. It can be operated in oxidising, inert and vacuum atmospheres.
- Quadrupole Mass Spectrometer (QMS) is coupled to the Simultaneous Thermal Analyser (STA) with a silicon carbide furnace which operates up to 1600°C. The heated transfer system operates up to 350°C. Mass range: 1 to 512u. Detection limit: 100 ppb with a scan rate: 100 u/s. The system analysis software provides identification of substances against a material library. The system has the capability to perform calibration for quantified analysis.
