Five Isotherm Examples
Moisture Sorption Applications
If you want to know how to actually use moisture sorption isotherms in your R&D efforts, here are five examples of groups that have done just that.
Example 1: Make component mixing models
Example 2: Set QA/AC specifications
Example 3: Define critical control points
Example 4: Do packaging calculations
Example 5: Predict the effects of temperature abuse
