Overview

About this webinar

 

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.

TGA-Sorption can be used to study drying processes or the adsorption and desorption behaviour of moisture. 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. The TGA-Sorption System allows you to precondition samples at temperatures up to 150°C and to increase or decrease the relative humidity.

In this webinar, we will discuss the basic principles of the TGA-Sorption System and present some interesting applications. Specifically, the webinar will cover the following topics:

  • Basic Principles of TGA-Sorption
  • Why Use TGA-Sorption?
  • Relative Humidity Calibration
  • Industries and Applications
  • Application Examples
