Simultaneous Thermal Analysis - STA (TGA/DSC)

Simultaneous Thermal Analysis - Thermogravimetry / Calorimetry

Simultaneous TGA-DTA/DSC measures both heat flow (Differential Scanning Calorimetry) and weight changes (thermogravimetry) in a material as a function of temperature or time in a controlled atmosphere. Simultaneous measurement of these two material properties not only improves productivity but also simplifies interpretation of the results. The complimentary information obtained allows differentiation between endothermic and exothermic events which have no associated weight loss (e.g., melting and crystallization) and those which involve a weight loss (e.g., degradation).

The LINSEIS STA Platinum Series (Simultaneous Thermal Analysis) can be used to determine simultaneous changes of mass (TG) and caloric reactions (DSC) of a sample in the temperature range from –150°C up to 2400°C. The unique characteristics of this product are highest precision, highest resolution and long term drift stability. The STA Platinum Series was especially developed to meet the challenging demands of the high temperature as well as low temperature applications. To cover this broad range, several specifically designed furnace types are available. Furthermore MS (Mass Spectrometer) and FTIR Spectrometer couplings can be added to receive unique additional information. Due to its superior performance, user friendliness and modularity, the Linseis Simultaneous Thermal Analysis devices are an indispensable tool for every thermo analytical user.

From the combination of TG and DTA / DSC / HDSC one receives a broad range of information, such as:


  • Mass change
  • Absolute sample temperature 
  • Temperature difference (sample / reference)


  • Enthalpy, melting energy
  • Specific heat
  • Glass point
  • Crystallinity
  • Reaction enthalpy
  • Thermal stability
  • Oxidation stability
  • Aging
  • Purity
  • Phase transformation 
  • Solidus / Liquidus - relationship
  • Eutecticum 
  • Polymorphism 
  • Product identification
