Calorimeter and Thermal Analyzer

A calorimeter measures heat from chemical reactions, physical changes, and heat capacity. Common types include bomb calorimeter, differential scanning calorimeter (DSC), isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters. Drawell’s calorimeter is widely used in thermodynamics, chemistry, and biochemistry.

How to Choose the Right Calorimeters?

For measuring total heat, choose a bomb calorimeter;

For measuring heat changes during the measurement process, choose a differential scanning calorimeter (DSC).

  • Bomb calorimeter: determining the calorific value of energy substances such as coal, biomass, and fuel oil; measuring the calories (total energy) of food; studying the combustion efficiency of substances.
  • Differential scanning calorimeter (DSC): studying the melting point and glass transition temperature of materials; analyzing the curing and crystallization processes of polymer materials; measuring specific heat capacity; evaluating the purity or stability of pharmaceuticals.

If Yes, and the total calorific value is required: a bomb calorimeter is the only choice.

If No, or non-destructive (e.g., plastics, films, pharmaceuticals): a DSC must be selected.

If Yes (e.g., wanting to know when plastic melts at 176°C): a DSC must be selected, as it provides a continuous temperature-heat flow curve.

If No, only a total calorific value is needed: a bomb calorimeter is sufficient.

A thermogravimetric analyzer or Thermal Gravimetric Analyzer(TGA) is a measurement of the mass of a sample as it changes over time as the temperature changes. Mass, temperature and time are considered the basic measurements in thermogravimetric analysis, and many other measurements can be derived from these three basic measurements.

What Instruments can a TGA be Coupled with?

TGA-FTIR (Fourier Transform Infrared): Real-time analysis of the functional groups in escaped gases to determine their composition.

How TGA–FTIR Works?

The combined use of thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR) is a powerful analytical technique for simultaneously monitoring the thermal decomposition process of materials and the composition of gaseous products.

  • TGA → Record when and how much weight is lost during sample heating
  • FTIR → Analyze and identify the chemical substances in the emitted gases in real time.

How to Choose Between TGA and DSC?

  • For measuring mass change, TGA (Thermogravimetric Analysis) is recommended.
  • For measuring heat change, DSC (Differential Scanning Calorimetry) is recommended.
  • TGA: TG curve (mass-temperature) and DTG curve (rate of weight loss).
  • DSC: DSC curve (endothermic/exothermic heat flow-temperature).
  • TGA: Provides decomposition temperature, thermal stability, and the content of each component (e.g., moisture, ash).
  • DSC: Provides phase transition temperature and enthalpy (melting, crystallization), glass transition temperature (Tg), curing reaction, and specific heat capacity.
  • TGA: Analyzes decomposition, oxidation, volatile matter, and determines ash/filler content.
  • DSC: Studies melting, crystallization, curing, phase transitions, drug purity, and material stability.
