Determination of glass transition temperature-DSC

Application:

DSC-500 is an intelligent, miniaturized and unit combining thermal analysis instrument type, which can be used in the melting, solidification, decomposition, chemical combination, reduction, oxidation and crystallization of the material, the production of the phase diagram, the development of the catalyst. With convenient data processing system and calculation method for the epitaxial starting temp, enthalpy variable, glass transition temp, enthalpy ratio, oxidation induction time(OIT), specific heat and kinetic parameters(DSC-500A is used for OIT test.), it provides an analysis method for organic, inorganic, polymer, mineral, petrochemical products, textile, medicine, etc. Functions like magnificaton and narrowing of the graph make the friendly interface easy to operate.

The instrument features:

• LCD liquid crystal blue backlight display, display information is very more, including setting temperature, sample temperature, oxygen flow, nitrogen flow, differential thermal signal, all kinds of switch state
• USB communication interface, universality, communication and reliable don't interrupt, support from recovery connection function.
• Furnace body structure is compact, Temperature rise rate arbitrary adjustable. To improve the installation process, all adopt mechanical fixed way, completely avoid the furnace internal colloid to differential thermal signal pollution.
• Double temperature probe, ensure that the height of the sample temperature measurement repeatability. The temperature probe installed in the furnace wall, used in PID control the whole furnace temperature, but due to the temperature of the thermal inertia, conduction to the temperature of the sample has certain deviation, and the deviation degree of four seasons are different, therefore, by a single temperature probe temperature control and temperature measuring, whether differential thermal signal or temperature signal, the error is large; The instrument in the sample bottom install a temperature probe to measure the real temperature of the sample, and use our special temperature control technology, control furnace wall temperature makes the sample temperature reach setting temperature.
• Digital gas mass flow meter automatic switching two way atmosphere flow, switching speed, stable time is short.
• Mark with standard samples, the convenience of our customers correction constant temperature coefficient.
• Furnace cooling interface, the convenience of our customers rapid cooling.
• Software adaptive each resolution computer screen, the software automatically according to the computer screen size adjust every curve display mode. Support notebook, desktop, Support Win2000, XP, VISTA, WIN7 operating system, etc.
• Support user programming procedures, to realize the automation of measuring steps. The software provides dozens of instruction, the user can according to your own measurement steps, agile combination each instruction, and save. Complex operation is simplified into a key operation.
