INSTRUMENT NAME & MODEL: Thermogravimetry Analyzers - TA Instruments Discovery TGA 5500

Thermogravimetric analyzers (TGA) measure weight change (loss or gain) and the rate of weight change as a function of temperature, time, The TGA 5500 is TA Instruments’ highest performance thermogravimetric analyzer. It provides superior sensitivity and baseline performance through patented Hi-Res™ and MTGA™ (Modulated TGA) technologies, enabling advanced material characterization across a wide temperature range.

CATEGORY: THERMAL LAB

Special Features

SPECIAL FEATURES
1. Hi-Res™ TGA technology: dynamically adjusts heating rate for optimized resolution of overlapping weight-loss events
2. MTGA™ (Modulated TGA): provides direct, real-time kinetic information
3. Ultra-sensitive Tru-Mass™ balance: resolution of 0.1 μg with high weighing accuracy
4. Wide temperature range: ambient to 1,200 °C
5. Linear controlled heating rates of 0.1 to 500 °C/min
6. Ballistic heating rates >1500 °C/min for the highest efficiency available
7. Programmable gas switching and control (inert, oxidizing)

Applications

1. Thermal stability, oxidation, and decomposition studies of polymers, composites, and pharmaceuticals
2. Quantification of moisture, volatiles, additives, filler content, and ash residue
3. Kinetic studies for degradation
4. Compositional analysis
