  • DIFFUSION AND SORPTION FREE GASKETS FOR GAS EXCHANGE MEASUREMENT SYSTEMS
    Publication number: 20110304105
    Abstract: Gaskets are provided for use in gas exchange measurement systems used for photosynthesis, respiration and transpiration measurements. Novel gaskets and gasket designs are provided, including composite gasket designs, along with corresponding construction techniques, which effectively provide low diffusion through bulk material, significant reductions in interfacial diffusion, sufficient compliance to conform to surface irregularities under low applied stresses, and/or low sorption properties, particularly of H2O vapor.
