TA Instruments Discovery 5500
Thermogravimetric Analyzer (TGA)
Acquisition
Acquired in 2023 through matching funds between AMSEC and Western Washington University Fraser Endowment for Equipment for the Sciences Fund. The 5500 TGA replaced an 18 year old model from the same manufacturer.
Features
- Tru-Mass™ balance with ultra low drift
- IR furnace for fast heating and cooling
- Precise atmosphere control (N2 and Air)
- HiRes™ TGA with heating rate controlled by mass loss rate
- MTGA™ Modulated TGA for model-free kinetic data
