Thermogravimetric analyzer (TGA) monitors sample weight loss caused by volatilization and degradation often as a function of temperature ramping using a high precision balance and furnace. Typical samples include polymers, epoxies, fibers and laminates for investigating deformulation, thermal stability, or comparative study applications. TGA only measures the mass loss caused by evolved gas events.
By coupling TGA with an FTIR, unique spectroscopic data as well as functional group information of the evolved gases may be now obtained.
The aims of this application note are to detail the PIKE TGA-FTIR Accessory, and present sample data.
