Gas Diffusion Analyzer

Gas Diffusion Analyzer

The PMI Gas Diffusion Analyzer is designed to determine the transport properties of various gases through sheet-like materials under a wide range of static and dynamic conditions. These measurements can be used to simulate real-world applications. The instrument is equipped with a mass spectrometer to detect extremely low transfer rates, enabling testing under very small gradients of concentration, pressure, or temperature. It is ideal for delicate sheet-like materials such as fabrics, films, laminates, paper, plastics, and boards with thicknesses up to 1.25 inches. Its versatility and ease of use make it an excellent research tool for characterizing dynamic material properties under both standard and non-standard conditions.
