Innovation application: Thermogravimetric Analysis

Title Thermogravimetric Analysis

Thermogravimetric analysis for determination of temperature influence on the materials weight changes is proposed. Thermogravimetry allows to acquire quantitative information on the composition and thermal stability of many different types of materials. The method is fast and can even be used for small-sized samples

Keywords TGA, thermogravimetric analysis, thermal stability

Description of the technology

Thermogravimetry is a technique that measures the change in weight of a sample as it is heated, cooled or held at constant temperature. The technique allows to characterize materials with regard to their composition. Determination of thermogravimetric properties of materials is proposed from room temperature to 1000oC temperature, both in an inert and oxidative environments by using TGA 1 thermogravimetric analyzer (Mettler/Toledo).
