Thermogravimetric Analyzer TGA Q5000 IR

The Q500 is the world’s #1 selling, research-grade thermogravimetric analyzer. Its field-proven performance arises from a responsive low-mass furnace, ultrasensitive thermobalance, and efficient horizontal purge gas system with mass flow control. Excellent for low-level detection of impurities, kinetic studies,off-gas analysis, and for high heating rate operation. Its design integrates a thermobalance engineered for maximum baseline flatness and high sensitivity, with the power and flexibility of an infrared furnace, and a proven horizontal purge gas system. The Q5000 IR surpasses other models with its new infrared furnace that offers the widest range of linear (0.1 to 500˚C/min) and ballistic (>2000˚C/min) heating rates from ambient to 1200˚C.

TA Instruments TGA 2950

Thermogravimetric Analysis (TGA) measures the amount and rate of change in the weight of a material as a function of temperature or time in a controlled atmosphere. Measurements are used primarily to determine the composition of materials and to predict their thermal stability at temperatures up to 1000°C. The technique can characterize materials that exhibit weight loss or gain due to decomposition, oxidation, or dehydration. It is especially useful for studying polymeric materials, including composites, but also is widely applicable to other organic materials, such as lubricants and edible oils, and to a wide range of ceramics, metals and other inorganics.
