Novel Permeability Tester
We are currently working with Queen Mary, University of London to develop a novel Permeability Tester based on our Clark electrode and a software analysis system. Using the system it will be possible to measure the effective diffusion coefficient of Biological & Polymer membranes for both Oxygen and Organic molecules. The system is expected to consist of 4 parts:
- The Clark Electrode acting as the sensor
- The controller consisting of the potentiostat circuits with data logging
- The software
- A standard PC
A typical determination can be completed in 5-10 minutes depending on the membrane and its diffusion coefficient.
The functional information that will be readily provided is:
- The porosity of a material
- Resistance to small molecule transport
- Stability and integrity during use
- Effects of ageing in the environment
- Surface fouling
- Adherence to industry standard requirements for specific barriers
It is expected that the measurement will be important for a number of applications, but specifically:
- Food packaging materials
- Contact lens materials
- Microbial and protein biofilms
- Porous meshes
- Textiles
- Paints and coatings
- Biological tissues
- Separation membranes for filtration, desalination and dialysis
- Sealants and adhesives
- Electronic packaging materials
