More information
- The contribution of weakly bounded protons in a material can be determined with this method. Therefore the moisture distribution at a certain time in materials or a combination of materials can be determined. Also the changes of the profiles, e.g., during a water uptake experiment or during a drying experiment, can be determined.
- The procedure can be used to determine the penetration depth of hydrophobic agents, impregnations or stone strengthening agents.
