摘要： 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.
