Discovery 5500 TGA (TA instruments)
Thermal gravimetric analysis (TGA) is a method in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction).
Discovery 5500 TGA (TA instruments) equipped with auto sampler and high resolution capabilities due to the Hi-ResTM and Modulated TGATM. This instrument is the only system offering patented infrared heating technology which allow ambient to 1200°C temperature range, linear controlled heating rates of 0.1 to 500°C/min, ballistic heating rates >1500°C/min for the highest efficiency available, and fastest cooling for improved sample throughput. Hi-Res provide improved data acquisition due to better separation of broad and overlapping weight losses, increased productivity with better resolution, and Rapid survey over wide temperature range with excellent resolution.
