Thermogravimetric-infrared (TG-IR) Analysis Service

Thermogravimetric-infrared (TG-IR) analysis is a sophisticated analytical technique that combines thermogravimetric analysis (TGA) with infrared spectroscopy (IR) to study the thermal decomposition and chemical changes of materials. This method is particularly valuable for understanding the thermal properties and chemical transformations of environment-friendly materials, which are crucial for sustainable development and environmental protection.

Principles of Thermogravimetric-infrared (TG-IR) Analysis

TG-IR analysis operates on the fundamental principles of TGA and IR spectroscopy. TGA measures the mass changes of a sample as a function of temperature or time, providing insights into the thermal stability and decomposition characteristics of the material. Infrared spectroscopy, on the other hand, identifies the functional groups of the evolved gases by analyzing the absorption of infrared light, which is related to the vibrational modes of the chemical bonds present.

The coupling of these two techniques allows for a comprehensive analysis of both mass changes and chemical composition of the gases evolved during the heating process. This dual analysis provides a more detailed understanding of the material's decomposition and the identification of the byproducts formed.

Advantages of Thermogravimetric-infrared (TG-IR) Analysis

Enhanced Correlation between Thermal and Chemical Changes

TG-IR analysis provides a more direct link between the observed weight changes in the TGA and the specific chemical species being evolved, allowing for a deeper understanding of the material's behavior.

Identification and Quantification of Evolved Gases

The FTIR component of the TG-IR system enables the detection and quantification of the chemical species being released during the thermal processing of the sample, including minor or trace components.

Real-Time Monitoring

The coupled TG-IR system allows for the simultaneous, real-time monitoring of mass changes and evolved gas composition, providing a comprehensive and dynamic view of the material's behavior.

Expanded Analytical Capabilities

By combining the strengths of TGA and FTIR spectroscopy, TG-IR analysis can provide more detailed insights into the thermal stability, decomposition pathways, and chemical composition of materials, including those designed to be environmentally friendly.
