Characterization under Dynamic Humidity Atmospheres


Polymer and Pharmaceutical Materials Characterization under Dynamic Humidity Atmospheres

Steven R. Aubuchon
TA Instruments
Newcastle, Delaware


Traditional thermal analysis experiments were typically performed under inert atmospheres, with limited consideration of the effects of reactive or humid atmospheres. However, in practice it is virtually impossible to eliminate water from processing, storage or end-use of most materials. As such it is important to create and control dynamic atmospheres, and to measure thermal and mechanical properties taking into account the effects of water. Modern instrumentation now provides for the simultaneous direct control of both temperature and relative humidity, applied to both gravimetric and dynamic mechanical analyses. In this seminar, moisture sorption analysis will be introduced and discussed, as it relates to a wide range of organic and polymeric materials whose applications include pharmaceuticals, electronics, fuel cells, and packaging. Detailed examples from both gravimetric and dynamic mechanical analysis applications will be presented and discussed.
