Membrane Permeation Analysis (MPA)
Traditional permeation testing can be slow and fragmented, with testing limited to a single gas/vapor. Membrane Permation Analysis is the new solution, delivering multi-component data in a single experiment, all in one compact instrument for faster, more confident decisions.
What is Membrane Permeation Analysis?
Membrane permeation analysis is a method used in polymer and separation science to evaluate the transmission rates and competitive permeation of gases and vapors through membranes and barrier films, to assess how well these materials function under real-world conditions
- Global Application
The MPA Horizon transforms permeation analysis by enabling simultaneous measurement of multiple gases and vapours with high precision. Advanced sensors for oxygen, CO2, humidity and organic vapors allow for concurrent measurement of distinct gas and vapor transmission rates.
How does MPA work?
In a typical membrane permeation analysis experiment, a membrane is introduced to a controlled gas/vapor mixture on one side of the membrane under a continuous flow. As they permeate through the membrane to the other side of the membrane, there is a sweep gas that moves the permeated gas/vapors to the outlet sensors. These sensors track the changing concentrations.
