thermogravimetry
Gravimetric quantification of material composition
| investigation method | thermogravimetry |
| Device type and equipment | TGA Q500 (TA Instruments) |
| functional principle | Measurement of the change in mass of a sample as a function of temperature and/or time. |
| Typical applications | Quantification of material composition (plasticizers and volatile components), filler content, decomposition behavior, moisture content, drying times and temperatures, determination of the Curie temperature of metals |
| measurement technology | Standard TGA, high-resolution TGA under nitrogen or oxygen up to 1000 °C |
| Norms and standards | DIN EN ISO 11358, DIN 51 006, ISO 9924 |
| Requirements for sample | 50 µg to 1 g |
