Proven Excellence. Differential Scanning Calorimetry -DSC 500 Pegasus® Method, Technique, Applications Analyzing & Testing

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 A modular design facilitates the exchange of furnaces and sensors, making this intrument versatile for various applications. This system can operate over an extensive temperature range from -150°C to 2000°C, accommodating a wide array of thermal analysis needs. Ideal Sensor Positioning for Accurate and Precise Results The ability to precisely adjust sensor...

Elimination of Atmospheric Influences -Vacuum-Tight Design The vacuum-tight 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 simplifies measurement starts and streamlines pre-measurement checks without the need to log into a PC. The double hoist is designed to simultaneously...

Differential Scanning Calorimetry 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 signals, the heat-flow difference between sample and reference can be determined. The DSC 500 Pegasus® is in line with nearly every respective instrument and application standard, including: ISO 1 1357, ASTM E793, ASTM...

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 the specific heat capacity in the higher temperature...

Double 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.

Sensor types Various 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 be easily changed in less than a minute by the operator. Thermo- Temperature couple range 1 Upper temperature limit may deviate from the maximum temperature range...

Unique 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.

A 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. The...

Automatic 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 waiting...

Accessories to Create the Ideal Atmosphere Optimal measurement conditions can be attained through the utilization of high vacuum, high purity, and reduced oxygen environments. 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 controller. Both MFC systems allow software-controlled gas switching and purge gas...
