The pore size of my developed bone scaffold ranges within 100-500 microns as observed from SEM analysis. What is the best way out of BET and mercury intrusion porosimetry to test the the pore distribution, pore volume and pore size of my samples?
There are a bunch of methods established for the pore characterization, which you can choose any of them in accordance with the polymer physicochemical properties, approximate pore size, and chemomechanical stability.
1. Gas physisorption method (BET), pore size range: 0.2 nm -100 nm
2. Mercury intrusion, pore size range: 2 nm -100 micrometer.
3. Neutron and X-ray scattering, pore size range: 01nm - 100 nm
4. Electron microscopy, pore size rang: 1 nm - 10 micrometere
5. Thermoporometry, pore size range: 1 nm - 100 nm.
6. NMR relaxometery, microscopy, and spin echo, pore size range: 1 nm to mm size.
7. Capillary flow porometry or permporometery pore size range: 1.5 nm- 100 nm.
