By connecting a humidity generator to the TGA instrument, you can create different relative humidity levels inside the TGA oven. You can also create programs that progressively or dynamically change relative humidity values for a certain time and at a certain temperature to study how different materials and substances absorb and emit moisture. This is important for studying packaging materials and for optimal storage conditions for food. Below are some examples of how to use the sorption analysis. Here you customize methods depending on what materials you look at and what information you need. In other words, there is a great deal of flexibility in the equipment.

Moisture affects different materials in different ways, and by measuring how the moisture is absorbed and released, important information about the properties of the material can be obtained. It is measured at one or more fixed temperatures and at some humidity levels the time it takes and the amount of moisture absorbed or released. The process is important for packaging materials.

Many foods can be investigated with regard to determining the best conditions for storage or transport. You can also investigate how long you can store a particular food at a certain temperature and relative humidity before absorbing too much moisture.

Many polymeric materials absorb moisture and then get altered properties that may resemble when adding plasticizers to certain polymers to make them softer. The kinetics of this behavior can be studied using TGA sorption tests.

Different types of powder materials can be studied with TGA sorption. Sometimes you may mix different powders together and then they get completely different qualities than when they exist individually because of their different absorption and release of moisture.
