TGA Thermogravimetric Analysis

Thermogravimetric analysis is an analytical method used to determine the thermal stability and volatile component structure of a material by tracking the weight change that occurs when a sample is heated at a constant rate. This analysis method is a kind of thermal analysis technique. Thermogravimetric measurement is usually performed either as a function of temperature rise with constant heating rate or as a function of time, taking into account mass loss and temperature constant.

Thermogravimetric analysis is recognized as a powerful technique for the measurement of thermal stability of materials, including polymers. In this method, changes in the weight of a sample are measured as its temperature is increased. The moisture and volatile content of a sample is determined by this analysis. The instrument used in these analyzes basically consists of a highly sensitive balance to measure weight changes and a programmable oven to control the heating rate of the sample. The scale is located above the oven and is thermally insulated from the heat. To maximize the precision, accuracy and precision of weighing, the balance must be isolated from thermal effects.

Three different techniques are commonly used in thermogravimetric analysis:

• Dinamik In the thermogravimetric analysis technique, the temperature continues to increase over time as the mass is recorded. This technique allows simultaneous identification of how much gas is removed and the temperature at which it is formed.
• In the static thermogravimetric analysis technique, the temperature is kept constant while measuring the mass. This technique is used to obtain more information about a degradation occurring at a certain temperature, or to obtain information about the waistline of a material.It is used to investigate its ability to withstand a high temperature.
• In the quasi-static thermogravimetric analysis technique, the sample is heated over more than one temperature range and usually held in these ranges for a period of time until the mass stabilizes. This technique is ideal for investigating substances known to decompose in various ways at different temperatures and to better characterize how they decompose.

Data from thermogravimetric analysis is usually displayed with a graph representing mass as a function of temperature for dynamic thermogravimetric analysis.
