Thermogravimetric Analyzers – Differential Scanning Calorimetry [TGA-DSC]

This system consist of two parts:

  • Differential Scanning Calorimetry
  • Thermogravimetric Analyzers

Differential Scanning Calorimetry (DSC)

DSC, is a thermal analysis technique that looks at how a material’s heat capacity (Cp) is changed by temperature. A sample of known mass is heated or cooled and the changes in its heat capacity are tracked as changes in the heat flow. This allows the detection of transitions like melts, glass transitions, phase changes, and curing. Because of this flexibility, DSC is used in many industries including pharmaceuticals, polymers, food, paper, printing, manufacturing, agriculture, semiconductors, and electronics as most materials exhibit some sort of transitions.The biggest advantage of DSC is the ease and speed with which it can be used to see transitions in materials
The system is the DSC 8000 of Perkin Elmer. This is a new double-furnace design delivers the most accurate heat-flow measurements

  • Symmetrical design ensures that instrument response from sample and reference pans are always identical
  • Non-oxidating, chemically resistant platinum alloy furnaces
  • Controlled heating and cooling for the most accurate results

Typical applications for the DSC 8000:

  • Isothermal kinetics studies – Measure samples at a true constant temperature
  • UV curing in polymers – Rapid response measures even the fastest cures
  • Process and product improvement – Demanding industrial and academic research.

The whole system is equpied with suitable software to evaluate the measurements.

Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which changes in physical and chemical properties of materials are measured as a function of increasing temperature (with constant heating rate), or as a function of time (with constant temperature and/or constant mass loss). TGA can provide information about physical phenomena, such as second-order phase transitions, including vaporization, sublimation, absorption, adsorption, and desorption.

The system is the Pyris 1 of Perkin Elmer with A vertical design with a high sensitivity balance and quick response furnace. The balance is located above the furnace and is thermally isolated from it. A precision hang-down wire is suspended from the balance down into the furnace. At the end of the hang-down wire is the sample pan. The sample pan’s position is reproducible.
