Instrument Introduction:
Differential Scanning Calorimetry (DSC), as a classic thermal analysis method for studying the thermal effects of materials at controlled program temperatures, has been widely used in various fields of materials and chemistry, including research and development, process optimization, quality control, and failure analysis.

By using DSC method, we can study the phase transition of inorganic materials, the melting and crystallization process of polymer materials, the polymorphic phenomenon of drugs, the solid/liquid phase ratio of foods such as oils and fats, and so on.

In recent years, the differential scanning calorimeter DSC 204 F1 launched by the German company Naich Instruments has made new breakthroughs in the structural design and flexibility of the instrument. Its measuring unit is a cylindrical 3D heating silver furnace body, embedded with heating wires, and externally connected with cooling equipment. The high thermal conductivity of the silver furnace body ensures temperature uniformity inside the furnace body. The integrated electronic flow control system ensures precise flow control under different blowing and protective atmospheres. The structural design of its airtightness allows the outlet end of the furnace to be connected to infrared or mass spectrometry for component analysis of the product gas.

According to the application field and actual needs, users of DSC 204 F1 can freely choose two different types of sensors. The time constant of the τ - type sensor is only 0.6 seconds, ensuring good separation ability for overlapping thermal effects. The μ - type sensor has a sensitivity that is more than ten times higher than ordinary sensors while ensuring peak separation ability, making it particularly suitable for small sample size research in fields such as pharmaceuticals, food, biomaterials, and liquid crystals.

DSC 204 F1 offers four different cooling methods: liquid nitrogen, mechanical refrigeration, air compression, and cooling cup. The use of a new mechanical cooling system can cover a measurement temperature range from -85 ° C to 600 ° C. Of course, if a liquid nitrogen cooling system (LN2) is chosen, it can provide a wider temperature range for measurement, from -180 ° C to 700 ° C.

Other special features and options include the 64 sample grade automatic sampling system ASC, a new ultraviolet light accessory, intelligent BeFlat correction function, advanced DSC correction, temperature modulation DSC (TM-DSC), etc. All of these make the DSC 204 F1 Phoenix^® Becoming one of the flexible and powerful DSC systems in today's market.
