TA Instruments offers the world’s most comprehensive line of High-Pressure Thermogravimetric Analyzers, equipped with TA’s proprietary Magnetic Suspension Balances. Discovery HP-TGA and DynTHERM TGA are designed for scientists who need to accurately weigh their materials in the widest range of temperature and pressure in reactive atmospheres or steam.

Adding the 3rd Dimension to Thermogravimetry

Standard thermogravimetric analysis (TGA) is frequently applied to measure the weight of a material as function of temperature, but standard TGA does not provide sufficient information under extreme conditions. Many materials are exposed to not only high pressure, but also humidity or reactive gas atmospheres in their normal use. In these cases, testing materials with high-pressure TGA provides a genuine assessment of stability, decomposition and lifetime.

Discover the following TA Instruments product lines of high-pressure thermogravimetric analyzers with industry leading specifications:

  • The Discovery HP-TGA is the world’s first fully integrated benchtop high-pressure TGA with TA’s patented top loading Magnetic Suspension Balance. The Discovery HP-TGA analyzers provide extraordinary specifications while being as easy to operate as any TA Instruments Discovery TGA instrument. Getting great high-pressure data has never been so easy!
  • The DynTHERM TGA feature the classical Rubotherm Series Magnetic Suspension Balance and cover the widest temperature range of all HP-TGA instruments. DynTHERM TGA analyzers provide a high weighing capacity and large sample volume for measurements with representative samples of inhomogeneous materials or testing complete assemblies.
