TGA Thermogravimetric Analysis: An Overview
Thermogravimetric Analysis (TGA) is an essential analytical technique used to measure the amount and rate of weight change of a material as a function of temperature or time in a controlled atmosphere. This method provides vital insights into the thermal stability and compositional properties of materials, aiding scientists and engineers in understanding how substances respond to environmental conditions. TGA thermogravimetric analysis is particularly critical in the fields of materials science, polymers, pharmaceuticals, and more.
Types of TGA Thermogravimetric Analysis
TGA is categorized into several types based on the nature of the analysis and the context in which it is applied. Here are some types of TGA thermogravimetric analysis:
- Dynamic TGA: Measures weight changes in real-time as temperature ramps up or down.
- Isothermal TGA: Observes weight change at a constant temperature over a period.
- Derivative TGA (DTG): Analyzes the rate of weight loss to identify decomposition steps more clearly.
- Simultaneous TGA/DSC: Combines TGA with Differential Scanning Calorimetry for comprehensive thermal analysis.
