The Membrane Permeation Analyzer (MPA Horizon) is a self-contained cross-flow gas permeation device designed to study the competitive permeation of gases and vapors through barrier films and membranes.
To ensure a comprehensive assessment of membrane performance, it can perform multi-component analysis and test important parameters like oxygen transmission rate (OTR) and water vapor transmission rate (WVTR).
Environmental factors, particularly temperature and humidity, can affect the permeation of gases or vapors through most membranes. The MPA Horizon allows permeation kinetics and gas/vapor permeation to be tested in real-world scenarios.
