Differential Scanning Calorimetry (DSC) is one of the frequently employed thermal analysis methods. It can be used to analyze nearly any energetic effect occurring in a solid or liquid during thermal treatment.
Easy handling and rapid analysis are among the hallmarks of this analytical technique, which has proven to be highly significant in the areas of research, development, and quality control. There are a variety of standards (ASTM, DIN,ISO, etc.) for the application, evaluation and interpretation of specific materials, products and properties.
The DSC 3500 Sirius operates according to the heat-flux principle. With this method, a sample and are ference are subjected to acontrolled temperature program(heating, cooling or isothermal).The actual measured properties are the temperature of the sample and the temperature difference between sample and reference. From the raw data signals, the heat flow difference between sample and reference can be determined which represents the caloric changes of the sample.
The gas-tight DSC 3500 Sirius combines the advantages of modern technology, high sensitivity and a robust, easy-to operate workhorse. Tests can be carried out in the temperature range between-170°C and 600°C.
Key components of the DSC 3500 Sirius are the DSC heat-flux sensor, the furnace and clever connection fittings which are designed for the quick and easy attachment of various cooling systems.
The sensor of the DSC 3500 Sirius combines high stability and optimized resolution of thermal effects. Laserguided welding processes for the sensor disks and thermocouple wires yield true sensitivity and robustness.
DSC features:
• Determination of onset, peak, inflection and end temperatures
• Automatic peak search
• Transformation enthalpies: analysis of peak areas (enthalpies) with selectable baseline and partial peak area analysis
• Evaluation of Crystallization
• Comprehensive Glass Transition analysis
• Automatic baseline correction
• Specific heat determination
• Tau-R® Mode: takes into account the time constant and thermal resistance of the instrument and reveals thus sharper DSC effects from the sample (optional)
• Optional TM-DSC (temperature modulation) for separation of reversing (thermodynamic) and non-reversing (kinetic) effects
