Simultaneous Thermal Analyzer – (TGA-DSC)

Thermogravimetric Analyzer TGA + Differential Scanning Calorimeter DSC

The LINSEIS Simultaneous Thermal Analyzer is a versatile tool that simultaneously tracks changes in mass (TG) and caloric reactions (DSC) across a wide temperature range, from -150°C to 2400°C. What sets this thermal analyzer apart are its exceptional precision, unmatched resolution, and remarkable long-term stability.

The STA Series was purposefully crafted to address the unique demands of both high-temperature and low-temperature applications. To cover this extensive range, we offer a variety of furnace options, each designed for specific requirements.

Additionally, the option to incorporate Mass Spectrometer (MS) and FTIR Spectrometer couplings can provide additional, invaluable insights. Thanks to its superior performance, user-friendly interface, and modular design, Linseis TGS and DSC analysis devices are indispensable tools for anyone in the field of thermal analysis.

Our diverse microbalances are meticulously designed to excel in thermal gravimetric analysis tasks. They feature an ultra-lightweight design to capture rapid weight fluctuations and boast a symmetric construction for exceptionally low-drift, long-term measurements.

  • For the analysis of food, pharmaceuticals,  building materials or biological processes
  • The other possibility is to measure under isothermal conditions

Water Vapor L40/WV

  • By mixing water vapor, produced in a water vapor generator, with a carrier gas like air, nitrogen or helium, variable concentration (in Vol.-%, wt.% or ppm) of the  water vapor in the sample gas can be adjusted within our analyzers .
  • The generator evaporates water without necessarily mixing the residual water vapor with other purge gases, which allows  100% H2O atmosphere at the sample .

Thermal method of STA

A Simultaneous TGA-DSC system concurrently records both heat flow (represented by the green curve) and changes in weight (illustrated by the orange curve) within a material as temperature or time progresses, all within a controlled environment. This simultaneous measurement of two fundamental material properties not only enhances efficiency but also streamlines the analysis of outcomes.

The invaluable complementary data acquired facilitates the distinction between endothermic and exothermic events that don’t entail any weight alteration (e.g., melting and crystallization) and events that do involve weight loss (e.g., degradation). This capability significantly simplifies result interpretation.

The application example gives an impression about the information obtained by a STA (TGA-DSC) measurement. The result provides information about the exact composition of the cement sample as you can determine the amount of humidity, the quality and amount of the contained quartz as well as the temperature stability of the material.
