Concurrent Thermal Analysis comprises both thermogravimetry (TG) and differential thermal analysis (DTA). Separate TG and DTA units are used, thus allowing optimization of the size and shape of each specimen. Large specimens can be used for TG, while smaller specimens are used in DTA. Analysis of the samples is made concurrent by using one temperature controller to closely match the temperature of the two samples as they are heated or cooled at a precisely programmed rate. TG analysis can be run in a broad range of controlled environments including air, oxygen, inert gases, corrosive gases, and high-vacuum (5 x 10E-6 torr).

Features:

• Concurrent TG and DTA measurements from 20 to 1700^oC
• TG balance capacity up to 100 g with sample diameters up to 30 mm
• Mass change determinations to +/- 0.001 mg
• Heating rates up to 100^oC /min.
• Controlled environments including air, inert, vacuum, and corrosive gases
• All systems fully computer controlled

Applications:

Concurrent thermal analysis can be used to examine the time-temperature-environment relationships for high temperature materials. The ability to accommodate large samples allows the testing of real components in aggressive environments, simulating actual processing or operating conditions.
