Thermogravimetric Analysis (TGA)

Find the Right TGA Instrument for Your Thermal Analysis

Understand How Your Materials Change with Temperature

NETZSCH TGA instruments help you measure mass changes as a function of temperature, time and atmosphere. Characterize Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability, Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition behavior, composition and OxidationOxidation can describe different processes in the context of thermal analysis.oxidation processes with reliable thermal analysis solutions.

Why Use Thermogravimetric Analysis?

Gain clear insight into Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability, composition and mass-loss behavior.

Thermogravimetric analysis measures changes in a sample’s mass under controlled temperature and atmosphere conditions. It supports material characterization throughout research, development and quality control. 

Evaluate Thermal Stability
 
Identify temperature ranges in which your material remains stable and detect the onset of mass loss.
Analyze Decomposition Processes
Examine one or multiple mass-loss steps and investigate the thermal behavior of complex materials.
Determine Composition and Residual Content
Assess volatile components, fillers, moisture, Ash ContentThe ash is a measure of the mineral oxide content on a weight basis. Thermogravimetric analysis (TGA) in an oxidative atmosphere is a well-proven method to determine the inorganic residue, commonly referred to ash, in organic materials such as polymers, rubbers, etc. Therefore, the TGA measurement will identify if a material is filled and calculates the total filler content.ash content or residual mass, depending on the material and test method.

What Can TGA Help You Investigate?

The appropriate temperature range, crucible, gas atmosphere and heating rate depend on the sample and the measurement objective.

How Does TGA Work?

In a thermogravimetric analysis, a sample is continuously weighed while it is heated, cooled or held at a defined temperature under a controlled atmosphere. The resulting curve shows mass change as a function of temperature or time.

  • Prepare the sample
  • Define temperature program and gas atmosphere
  • Measure mass change during the test
  • Interpret the TGA curve and derivative signal (DTG), if required
