Nano-PermPrometer
Nano-PermPorometer
For evaluation of nano-order pore size membranes
Patent No.3291691
Measurable Properties
Pore size distribution
Several Gas permeability
Water & Hexane vapor permeability
Separation Factor of condensed gas and no condensed gas
Principle & Formula
The basic principle of Nano-PermPorometry is based on the capillary condensation of a vapor and its ability to block the permeation of a non-condensable gas.
- Kelvin equation
