Differential Scanning Calorimetry – DSC 500 Pegasus® Method, Technique, Applications Analyzing & Testing
Open the catalog to page 1Outstanding Features DSC 500 Pegasus® At NETZSCH, we mastered the challenge of high-temperature DSC measurement years ago. Today, that same drive for perfection allows us to consistently offer the best solution on the market. Modular Design for the Broadest of Temperature Ranges Ideal Sensor Positioning for Accurate and Precise Results The Right Sensor For Each Application The modular design facilitates the easy exchange of furnaces and sensors, making it versatile for various applications. This system can operate over an extensive temperature range from -150°C to 2000°C, accommodating a...
Open the catalog to page 2Elimination of Atmospheric Influences – Vacuumtight Design Color Touch Display and LED Status Bar Efficient Time Management The vacuumtight design and meticulous control of gas flows allow precise handling of high-purity atmospheres with respect to various inert, oxidizing, reducing, and corrosive gases. Enthalpy changes and specific heat capacity (cp) can be analyzed with an unequalled level of accuracy. The color-coded LED light bar allows for remote monitoring of the instrument status. The integrated display implifies measurement starts and streamlines pre-measurement checks without the...
Open the catalog to page 3Differential Scanning Calorimetry 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. The DSC 500 Pegasus® systems operate 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...

Open the catalog to page 5Modular Design – Interchangeable Furnace Systems The DSC 500 Pegasus® systems can be equipped with a wide range of different furnaces accommodating different temperature and application ranges between -150°C and 2000°C. Silver and steel furnaces are available for the sub-ambient temperature range. Controlled cooling is realized with the liquid nitrogen cooling device or the Vortex tube. For higher temperature ranges, SiC, Pt, Rh and graphite furnaces are available. The platinum and the rhodium furnaces in combination with dedicated DSC sensors are specifically suited for determination of...
Open the catalog to page 6Double Hoist The electrically driven double furnace hoist is a standard feature of the DSC 500 Pegasus®. It allows for simultaneous installation of two different furnaces to conduct, for example, low- and high-temperature tests with the same instrument. For an improved sample throughput, it is also possible to connect a single furnace along with the automatic sample changer (ASC) instead. Graphite furnace Furnace evacuation Micrometer screws for simple adjustment of the sample carrier Instrument evacuation DSC 500 Pegasus® with graphite and SiC furnace
Open the catalog to page 7Various Sensors The DSC 500 Pegasus® instruments are generally used to obtain accurate specific heat (cp) measurements. However, the system allows for simple DTA measurements or conventional DSC tests as well. DTA sensors can be used for applications such as routine tests on aggressive sample substances. Various thermocouple types allow for optimum sensitivity and time constants in all temperature ranges. The sensors can easily be changed in less than a minute by the operator. Interchangeable Sensors Temperature range Sensor types Oxidizing Reducing1 Vacuum Corrosive Upper temperature limit...
Open the catalog to page 8Unique Sensor Adjustment System For optimizing the baseline, a micrometer adjustment system is integrated into the measurement part. This adjustment system allows for placement of the sensor at the optimum central position in the furnace. This creates a stable and reproducible baseline without any major adjustment efforts. DTA sample carrier (protected version) DTA sample carrier for temperatures up to 2000°C DSC cp sample carrier with platinium crucibles DSC cp sample carrier for ASC operation (with OTS®)
Open the catalog to page 9A Wide Variety of Crucibles Platinum Crucible with Liner and Shaping Tool What sets the DSC 500 Pegasus® systems apart is not only their flexibility in furnaces and sensors but also the huge variety of available crucibles. For the broad temperature range from -150°C to 2000°C, the crucible materials vary from metals (Al, Ag, Au, etc.) to ceramics (Al2O3, MgO, ZrO2, Y2O3, BN, etc.) to graphite. For inhomogeneous samples and those with low density, larger crucibles are available. Our platinum crucible and Al₂O₃ liner combination improves the accuracy of high-temperature metal analysis in STA....
Open the catalog to page 10Automatic Sample Changer (ASC) An automatic sample changer for up to 20 samples is optionally available. The sample changer is designed for optimum crucible placement and maximum throughput. Preprogramming allows measurements to be carried out during the night or weekend. The software can automatically carry out analyses using automatic or predefined evaluations. The ASC with its gripper and carousel can handle nearly any crucible type including specialties such as medium- and high-pressure crucibles. For unstable samples – i.e., samples sensitive to oxygen or ambient room conditions while...
Open the catalog to page 11Accessories to Create the Ideal Atmosphere Optimal measurement conditions can be attained through the utilization of high vacuum, high purity, and reduced oxygen environements. Atmosphere – Mass Flow Controllers Oxygen Trap System for Measurement Under Oxygen Free Atmospheres The DSC 500 Pegasus® comes standard-equipped with integrated metal-housed mass flow control systems for three different gases. Alternatively, the system can be equipped with frits for corrosive gas atmospheres or an optional fourth mass flow controler. Both MFC systems allow software-controlled gas switching and purge...
