Nano Perm Porometer

Utmost limited deformation and damage to sample are key factors for evaluating nano size pore distribution. BET requires to freeze sample at 77K, and Mercury Porosimeter needs to add pressure up to 60,000PSI. In contrast, nano-permporometry can measure by minimum differential pressure and from humid and dry environment. NPP realized measurements for hydrophobic and hydrophilic samples with using precise controlled water vapor and hexane vapor gases.

- No Destruction, No Mercury, No High Presusre Test - Auto-Test by Computer Control - Test Duration is Short - Hysteresis Measurement (Dry → Wet → Dry/ Wet → Dry → Wet) - Applicable for Hydrophobic and Hydrophilic Membranes
