TGA-Sorption Analysis – Principles and Applications
TGA-Sorption analysis yields valuable information to help study the effects of moisture on material properties.
The Advantages of TGA-Sorption Analysis
Product stability, processability and mechanical stability can be influenced by moisture and it is important to know how food products, powders or polymers react in a well-defined humid environment. The influence of humidity depends on the material or the constituents of the formulation or product. In general, the moisture absorbed by materials is classified either as free water or as chemically bound water.
Measurements under conditions of controlled relative humidity provide information that is crucial for understanding the effects that moisture content can have on the properties of a wide range of materials. TGA-Sorption analysis gives answers regarding processing, shelf life of products and structural properties.
Specifically, TGA-Sorption measurements can be used to determine sorption enthalpies as well as to calculate isotherms, BET and GAB plots, and surface coverage behavior. The method yields valuable information to help study the effects of moisture on material properties.
