There are many reasons why thermal analysis is conducted in materials science, but it is primarily used to obtain information on how a material’s behaviour changes when it goes through different temperature changes. Many methods can be used to monitor the changes, the most common being thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). However, in this blog post, we will focus on TGA, why a thermogravimetric balance is a suitable instrument for thermal analysis and how it works. 

What is a Thermogravimetric Balance?

A thermogravimetric balance, also called a thermobalance or thermogravimetric analyzer, comprises a...

Thermogravimetric Analysis (TGA) is an essential tool in materials science and quality control, offering insights into material composition and stability under varying temperature conditions. XRF Scientific, a leader in the field, provides advanced TGA solutions, including the xrTGA 1100 model, designed for high throughput and precision in diverse applications.

Types of TGA Testing

TGA testing can be broadly classified into three types based on the heating approach:

1. Isothermal (Static) TGA Testing: This method maintains a constant temperature while monit...

Thermogravimetric analysis (TGA) is a cornerstone in material characterization, offering a microscopic lens into the stability and composition of materials under thermal stress. This technique, pivotal for scientists and engineers, hinges on measuring mass change as a sample undergoes controlled heating or cooling. The interpretation of TGA results is not just about observing weight fluctuations; it’s about understanding a material’s story as it unfolds with temperature.

The Mechanics of TGA Instruments

At the heart of a TGA instrument lies a sample crucible, balanced and housed within a furnace where the thermal transformation occur...
