Introduction: Differential Scanning Calorimetry (DSC), as a classical thermal analysis method for controlling the thermal effect of program temperature, is widely used in various kinds of materials and chemistry research and development, process optimization, quality control and failure analysis Have long been in various occasions To a wide range of applications. Using the DSC method, we can study the phase transition of inorganic materials, the melting of polymer materials, the crystallization process, the polymorphism of drugs, the solid / liquid phase ratio of foods such as oil and fat. Features: 1. Heat-flow differential scanning calorimeters with good repeatability, high accuracy, especially for the precise measurement of specific heat. 2. Independent research and development of thermostat controller, thermostatic gas chromatography, mass spectrometer connector, temperature zone, can fully guarantee the tar and a variety of reactive gas secondary detection. 3. The whole machine integrates the temperature control and the furnace device to reduce the signal loss and interference. 4. Perfect two atmosphere control system, the use of mass flow controller; measurement process, you can choose two intake mode, the software settings automatically switch. 5. The instrument is equipped with a standard substance, the user can carry out the correction of each temperature section to reduce the error of the instrument. 6. Intelligent software design, automatic drawing of the whole instrument, the software can achieve a variety of data processing, such as enthalpy calculation, glass transition temperature, oxidation induction period, the melting point of the material and Crystallization and so on. 7. The instrument can automatically generate DSC and oxidation induction period of the experimental report. 8. Large-screen liquid crystal display, real-time display of instrument status and data, two sets of thermocouple, a set of galvanic display sample temperature when working, the other set of real-time display galvanometer temperature (no matter Furnace work or not). 9. The machine is equipped with RS232 and USB transfer interface, intelligent software, automatic program control and settings. 10. The instrument has a remote operation and maintenance, calibration function (through the Internet to remote operation of the instrument). Technical Parameters: Temperature data Temperature range: -150 ℃ ~ 680 ℃ (manual into the liquid nitrogen) Temperature accuracy: ± 0.1 ℃ Heating rate: 0.1 ℃ / min ~ 100 ℃ / min Temperature repeatability: ± 0.1 ℃ Temperature control methods: heating, constant temperature (automatic control program) DSC data Measuring range: ± 500mw Minimum resolution: ± 0.1μw Power noise: ± 0.1μw Power accuracy: ± 0.1μw Special feature Display: Chinese large-screen LCD display Crucible volume: 0.06 mL Atmosphere system: gas mass flow controller; two gas can be set to automatically switch Gas flow rate: 10 ~ 200mL / min Crucible configuration: aluminum oxide, high purity aluminum (standard)
