TGA - Thermogravimetric Analysis
Analytical technique
description
Thermogravimetric analysis (TGA) is an analytical technique dedicated to record mass variations of a studied sample in function of temperature or time, in a controlled atmosphere. The result of this kind of analysis is a thermic decomposition curve, which reports in abscissa temperature or time values and in ordinate mass variations as absolute or percentage values.
Applications
Thermogravimetric analysis (TGA) is an analytical technique dedicated to record mass variations of a studied sample in function of temperature or time, in a controlled atmosphere. The result of this kind of analysis is a thermic decomposition curve, which reports in abscissa temperature or time values and in ordinate mass variations as absolute or percentage values.
Basics
It is a method of thermal analysis in which changes in physical and chemical properties of a given material are recorded as a function of increasing temperature (with constant heating rate) or as a function of time (with constant temperature or constant mass loss).
Instrumental details
Sistema TGA Perkin Elmer, modello Pyris 6 (Florence Unit).
