A thermogravimetric analyzer (TGA) is extremely useful for quality control and learning about different materials, such as their decomposition patterns. Their main purpose is to measure samples of materials under a variety of temperatures to see what changes happen. Any changes in weight can also be calculated against time and atmosphere.

Polymer Industry

Within the polymer industry, TGAs are extremely important. This is because they can analyze:

• Thermoplastics
• Thermosets
• Elastomers
• Composites
• Plastic films
• Fibers
• Coatings
• Paints.

This makes them essential for assessing product quality and safety, as TGAs can measure the materials’ thermal and oxidative stability. For

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 thermometer, sample crucible and precision balance. It is placed within a furnace during an experiment, which is

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 monitoring the sample’s weight over time. It is particularly useful for studying long-term stability or slow thermal processes.
