Differential Scanning Calorimeter (DSC)
In DSC, the heat flow in and out of a sample and a reference material is measured as a function of temperature as the sample is heated, cooled or held isothermally at constant temperature. The measurement signal is the energy absorbed or released by the sample.
METTLER TOLEDO DSC 1 is used in our thermal analysis laboratories to determined Physical properties and processes like:
  • Crystallization
  • Glass transition
  • Melting point
  • Thermal stability
  • Solid-solid transitions and polymorphism
  • Pyrolysis
  • Chemical reactions such as thermal decomposition or polymerization
  • Comparison of different batches of product
 
Our DSC covers a temperature ranging from -150 to 700°C and the furnace chamber can be purged with nitrogen.
 
Thermogravimetric Analysis (TGA)
TGA is an experimental technique in which the mass of a sample is measured as a function of sample temperature or as a function of the time in isothermal experiments. The results of a TGA measurement are displayed as a curve of mass against temperature or time.
METTLER TOLEDO TGA/DSC1 instrument that is used in our thermal analysis laboratories, simultaneously measures heat flow in addition to weight change.
The effects that can cause a sample to lose mass include:
  • Evaporation of volatile constituents
  • Loss of water of crystallization
  • Oxidation of metals
  • Oxidative decomposition of organic substances
  • Thermal decomposition with the formation of gaseous products.
  
Our TGA covers a temperature ranging from RT to 1100°C and the furnace chamber can be purged with nitrogen.
