Product Overview

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.

Product Overview

 

Principle

If condensable vapor condenses at neck parts in pores in accordance with Kelvin equation, all pores under condensed radius in relation to vapor pressure are blocked by fluid of condensable vapor and Permeation of non-condensable gas decreases. With pore size, which is measured from this Permeation of non-condensable gas decrease and Kelvin Equation, pore size distribution of porous membrane can be figured out. In this time,the biggest flow rate decrease leads to peak of distribution.
