Ease of Use
Ease of Use
TRIOS software makes calibration and operation of the TMA 450 simple. Users can easily generate multiple calibration data sets under varying experimental conditions (e.g. different heating rates or gas selections) and seamlessly switch between them to match the experimental conditions used for sample testing. Real-time signals and the progress of running experiments is readily available, with the added capability of modifying a running method on the fly. TRIOS software offers a level of flexibility that is unmatched in the industry.
Quick & Easy Calibration
Quick & Easy Calibration
TRIOS software makes calibrating the sample fixtures/probes and the TMA 450 effortless. Clear instructions, available on both the touch screen and TRIOS software, guide the operator through simple calibration steps that end with a summary report. The report provides calibration status at a glance and is stored with each data file to ensure data integrity.

Humidity Applications
Assessing CHE
Assessing CHE
The expansion or swelling of a material due to water uptake is dependent on the material’s coefficient of hygroscopicity (CHE). The plot to the right measures this property for Kapton, an important polyimide used in the electronics industry. The plot is a sorption isotherm produced from a stepped humidity experiment. Also shown is the calculated CHE between successive points.
Comparing Hygroscopicity
Comparing Hygroscopicity
Perflurosulfonic Acid (PFSA) films, also known as proton exchange membranes, are used extensively in new battery technology. Many advanced polymers must be tested for responses to humid conditions. The plot to the right the comparison of the hygroscopicity of commercial film compared against the Kapton data above. The PFSA film has approximately an order of magnitude larger response to humidity than the Kapton.
Detecting Tg
Detecting Tg
Glass transitions are sensitive to water uptake, as the water acts as a plasticizer. Detecting and tracking changes in Tg are critical to material function and storage. The plot to the right shows the Tg of a gelatin used in pharmaceutical drug capsules captured with a RH ramp of 2%/min at 37 and 50°C. At higher temperatures, the Tg is shifted to lower RH levels due to higher water uptake and resultant plasticization.
Shrinking on Drying
Shrinking on Drying
Many materials shrink while drying, and it is important to be able to understand the forces involved. In the plot on the right, a polymer film is held under isostrain conditions of 0.2% and the force necessary to maintain this strain is tracked during a rapid change in humidity from 50 to 0%. The increase in force necessary to maintain the strain constant is clearly measured.
