Differential Scanning Calorimetry

Nishka Research – Your most reliable thermal testing partner. “Differential Scanning Calorimetry (DSC) / Differential Thermal Analysis (DTA)/ Thermogravimetric Analysis or Thermal Gravimetric Analysis (TGA).”

DSC Testing: Differential Scanning Calorimetry studies or DSC testing is a thermo analytical technique, which compute heat capacity (Endothermic/Exothermic) as a function of temperature or time”. In DSC analysis a known mass (small quantities in milligrams) of sample is heated or cooled at a pre program controlled temperature, which changes in heat capacities are scanned and output is recorded as graph. Output of DSC is known as Thermogram.

DSC thermogram reveals most valuable information of a material which includes Malting point (Tm), Glass transition temperature (Tg), Purity, Crystallinity, Specific heat capacity, Thermal stability, Curing temperature, Oxidative nature & Phase changes.
