​The Gas Diffusion Analyzer is used to determine the transport of various gases through sheet-like materials under a wide range of static and dynamic conditions, which in turn, can be used to simulate real-world applications. The instrument is equipped with a mass spectrometer in order to detect low transfer rates, which permits testing under small gradients of concentration, pressure, or temperature. This instrument is ideal for small and even delicate sheet-like materials such as fabrics, films, laminates, papers, plastics, and boards of thicknesses below 1.25 inches. The versatility and convenience of this instrument make it the optimal research tool for characterizing the dynamic properties of your material under both standard and non-standard conditions.
