| MODÈLE | TGA 8000 |
On this TGA, an optical null ultra-microbalance, isolated in a temperature-compensated balance chamber, ensures stability and provides the capability of measuring the smallest weight changes. With its two integrated mass-flow controllers, it is possible to purge the furnace (sample) and the balance with distinct gases. Its low mass and forced-air cooling allow it to cool quickly for fast sample turnaround. The TGA 8000 permits the analysis of volatile and humidity/air-sensitive samples through the Accupick accessory. The accessory has a needle that is attached to a stem fixed under the balance system of the TGA. When the autosampler is raised, the needle punctures the cover of the Accupik pan (made of aluminum). The pan capacity is about 30µL and is suitable to liquid and solid samples.
The TGA 8000 permits the study in a wide array like the decomposition and thermal stability, the component identification and quantification, the moisture/solvent evolution and identification and the study of reaction kinetics.
