| A method and a device for the analysis of gas components of a matrix employ two sensors, which each comprise a cavity enclosed by a membrane. Both membranes, each on one side of the matrix and on the other side, are exposed to a purge gas and subsequently, the timeline of the differential pressure Δps starting at a start time tA is measured, which is created between the sensors as a consequence of permeation of gas components of the matrix and/or the purge gas through both membranes. From the timeline, a point of time tE is determined, at which the measured differential pressure equals the differential pressure at the point of time tA, whereby the gas component of the matrix, which is different from the purge gas, and its genesis is determined from the time difference Δt=tE−tA. | ||||||

| A system and method of taking a sample of hydrogen gas and reducing the hydrogen concentration by a factor greater than 1×108 while increasing the partial pressure of the contaminating gases by a factor greater than 100, so that extremely low levels of contamination can be accurately detected. A sample of hydrogen gas is captured. Only the hydrogen gas is removed leaving all the contaminating gases in the collection chamber. This causes the total pressure of the gas sample within the collection chamber to decrease dramatically since most of the gas was hydrogen. All the contaminants remain in the collection chamber. None are lost through pumping. As such, the concentration of contaminants within the remaining sample increases dramatically. The residual partial pressures of the contaminating gases within the collection chamber and can now be measured by a variety of techniques. | ||||||

| The invention relates to a method for the determination of diffusion coefficients and/or exchange coefficient of a material having electronic and ionic conductivity. The material is permeable to at least one gas. It is the object of the invention to provide a cost-effective, accurate method for the determination of the diffusion coefficient and of the surface exchange coefficient which can be carried out in a short time and can thus be used for a screening of materials, in particular for application in the field of permeation membranes. The procedure is followed in accordance with the invention such that a sample of the material is arranged in a measurement chamber and has an electric current passed through it for a determination of the electric resistance. In this respect, a gas mixture in which the respective gas is contained is conducted through the measurement chamber as a gas flow and the partial pressure of the respective gas in the gas mixture is changed periodically at regular intervals. The change in the electric resistance of the sample is measured and a diffusion coefficient and/or exchange coefficient of the material can be determined for the respective gas from the determined change in the electric resistance. | ||||||

| An apparatus (10) monitors the condition of a component (12) by measuring the conductivity to air flow of a sealed cavity (14) formed on the surface of the component (12). The apparatus (10) comprises an unregulated pressure source (16) that is coupled to the cavity (14) via a fluid flow restriction (17). A measurement system (19) provides a measurement of, or related to, the volumetric air flow through the restriction (17), and calculates a conductivity index CI to air flow of the cavity in accordance with the equation CI=flow/pressure difference. In this equation “flow” is the volumetric flow of air through the flow restriction and “pressure difference” is the difference in pressure across the cavity with reference to atmospheric or ambient pressure. In the event that a crack traverses the cavity and provides a flow path to the atmosphere, the conductivity index CI will be a non-zero value. The higher the conductivity index the larger the crack. | ||||||
