TGA is a technique in which the weight of a sample is measured as a function of temperature whilst it is subjected to a controlled heating program. DTA is a technique in which the difference in temperature between the sample and an inert reference material is measured as a function of temperature. Again a controlled thermal programme is operative. TGA/SDTA refers to the application of two techniques to the same sample at the same time.

Key features of Mettler-Toledo TG/SDTA 851e.

• Wide measurement range ( 1 to 5 g)

• High resolution 0.1 to 1.0 mg

• Temperature range - room temperature to 1600^oC

• High temperature accuracy (+ 0.25 ^oC )

• Physical transitions observable on the SDTA curve.

Applications

The amount of weight lost during a TGA experiment provides quantitative in sight into the composition of a sample. Additionally, the temperature of thermal and oxidative degradation are measured. A wide variety of material behaviour and products can be investigated. Including volatilization, thermal degradation in an inert atmosphere (pyrolysis), reaction with oxygen or other reactive gases and amount of residual material (ash, filler).SDTA give melting, physical and chemical transitions of the sample.
