HIGH-RESOLUTION THERMOGRAVIMETRY

A new thermogravimetric instrument is introduced, Hi-Res(TM) TGA 2950. The Hi-Res(TM) TGA gives a significant improvement to TG results. The instrument control parameters are varied as a function of the sample's rate of weight change. This novel feature improves resolution and reduces analysis time. The maximum heating rate and resolution index are user selectable. Data presented demonstrate improved resolution for survey TG thermal curves and very high resolution for difficult to resolve complex materials. Results are demonstrated for many types of samples including: homopolymers, polymer blends, inorganic reference materials, and complex organic mixtures.
