摘要： Method and apparatus for carrying out analyses of a gas comprising one or more species Si, Sj, …, Sn by means of an ion mobility spectrometer which includes a plurality of electrodes (Ei) arranged in a chamber (C) divided by an electrifiable grid (G) into a reaction zone (RZ) provided with an inlet (IC) for the gas to be analyzed and a drift zone (DZ) provided with at least one ion detector (D), wherein said electrodes (Ei) generate at least one electric field (ERZ, EDZ) non-uniform in space along the axis (x) of the chamber (C).

摘要： Vacuum panel comprising a discontinuous or porous filling material (5) enclosed between at least two barrier sheets (6) mutually joined along the edges, between which are gas-tightly arranged one or more rheophores (7, 7') suitable for electrically powering at least one device (1, 2, 3, 3', 4, 4') arranged inside the vacuum panel, in particular a sensor for measuring the pressure (P) of the residual gases in the panel itself.
