Porosimeter Technology for Porous Size Distribution Characterization
Researchers at the Canadian Space Agency (CSA) have invented and demonstrated a liquid extrusion porosimeter which offers all of the advantages of existing liquid extrusion based techniques, while addressing the key requirements of high precision and repeatability. This novel method for pore size distribution function determination for capillary porous materials is derived from two key innovations; sample-liquid displacement tube leveling, and mass (not volume) based measurements.
Porosimeters are instruments that are capable of characterizing the size, volume, distribution, density, and other attributes of the porosity a given material. Materials that may require porosity characterization and analysis include ceramics, clays, pharmaceuticals, soils, cement, zeolites, metallic compounds and carbon sequestration materials. Using porosimeters, pore diameters that range from millimeter to nanometer are able to be characterized.
The porous materials test equipment market is a highly niche but growing segment of the overall analytical instrumentation value chain. The global market for porous material testing is expected at ~$3.75 billion by 2015-2016. This testing equipment is shared between the differing competing technologies, which include: mercury/nonmercury intrusion porosimters (bulk of the market), liquid extrusion porosimeters, permeameter, porometers, pycnometers, representative sampling equipment, sorptometers and water intrusion porosimeters.
The Business Opportunity
The porosimeter technology developed by CSA represents an opportunity for industry to (1) develop and offer a new porosimeter with advanced capabilities or (2) improve an existing porosimeter product line with the improvements embodied by the technology. A prototype porosimeter is available for demonstration. Provisional patent applications protecting the technology have been filed in USA and Canada. The CSA is seeking partners who are interested in licensing the intellectual property and know-how.
Technology Transfer Details
A commercialization license for this technology is available.
