Differential Scanning Calorimetry – DSC 3500 Sirius Method, Technique and Applications Analyzing & Testing

Differential Scanning Differential Scanning Calorimetry (DSC) is one of the most 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. Specific heat...

The DSC 3500 Sirius operates according to the heat-flux principle. With this method, a sample and a reference are subjected to a controlled 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. Reference signal Sample signal Transition temperature Area A ~ Transition enthalpy Difference (from 0) ~ Mass · cp The sample...

The gas-tight DSC 3500 Sirius combines the advantages of modern technology, high sensitivity and a robust, easy-tooperate 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...

AutoEvaluation to Identify AutoEvaluation automatically analyzes unknown curves of polymers and metal melts. AutoEvaluation* – Autonomous Evaluation for Polymers Identify* – A Step Ahead with the Database AutoEvaluation is a self-acting software package which evaluates glass transition temperatures, melting enthalpies or peak temperatures. For melting effects, for example, both the peak temperature and the enthalpy are determined; in the case of a glass transition, the software calculates Tg (the glass transition temperature) and the step height, expressed as Δcp. The Identify software...

RELIABLE RESULTS – THE BASIS FOR EFFECTIVE WORK Stable Baselines & High Repeatability Smart Furnace – Sensor Design The heating wires of the furnace surround the entire sensor plate. They are arranged in such a way that no temperature gradients occur in or above the sensor disk. 2.60 °C, 0.008 mW This arrangement is the basis for a highly homogeneous heat flow to the sample and reference pans from all sides and therefore also for a very stable baseline and an optimum signal-to-noise ratio. Value: -100.0 °C, 0.004 mW Value: -100.0 °C, 0.009 mW Value: -100.0 °C, 0.010 mW Value: 300.0 °C,...

Compact Design – Fits into Any Corner of Your Lab Gas-Tight – A Prerequisite for OIT Tests Economic Cooling – User-Interchangeable Devices The DSC 3500 Sirius features a particularly slim design requiring only a small footprint. A clever solution for sample handling is provided by the metallic shelf on top of the DSC system. The gas-tight measurement cell offers defined atmospheres for optimum measurement conditions. Three magnetic valves control the gas flows and are on/off programmable. Alternatively, mass flow controllers are optionally available. These features all positively affect the...

Automatic Sample Changer SUPERVISION RELINQUISHED For applications with high sample throughput, an automatic sample changer (ASC) for up to 20 samples and references is available. Besides standard aluminum pans, the ASC can accommodate pressure-tight crucibles (autoclaves), ceramic and metallic sample pans. Transport safety is provided by the four arms of the gripper. This mechanism safely removes the crucible from the magazine and places it carefully – without jiggling – into its position on the sensor. The reference crucible can also be changed out as often as the application requires....

Light-Curing via UV Add-On Besides thermally activated reactions, which can be studied by conventional Differential Scanning Calorimetry (DSC), many polyaddition reactions and radical polymerizations can also be started by irradiation with sufficiently high energy. For the DSC 3500 Sirius, we offer a UV add-on consisting of a UV lamp and controller, a pulse generator for shutter control, and a UV fiber lid with a lid rest for convenient handling. Advantages of Photo-DSC Tests Extending the DSC technique with light radiation capability Analyzing photo-initiated reactions in a broad variety...
