Claim Text:
1. A ion mobility spectrometer chamber, FAIMS type, with an inlet and outlet for the analyzed gas, a heating resistor, an ionizer of the gas flowing through, a FAIMS detector and electrodes collecting ionic current, where the FAIMS detector comprises two electrodes separated by a gap, to which a high voltage, high frequency current is connected, characterized in that the heating resistor ( 7 ), the ionizer electrodes ( 10 ), the HV detector electrodes ( 11 ) and the collecting electrodes ( 12 ), as well as the conducting contacts ( 13 , 14 , 15 ), are applied in the form of layers of precious metals on ceramic plates ( 3 , 4 ), where the heating resistor ( 7 ) is located on the outer surface of the top ( 3 ) and bottom ( 4 ) ceramic plate in the form of a resistive layer of ruthenium dioxide, on the inner surface of each of the top ( 3 ) and bottom ( 4 ) ceramic plates, sequentially, starting from the gas inlet ( 1 ) to the chamber, there are gas ionizer electrodes ( 10 ) in the form of a layer of radioactive nickel, HV electrodes ( 11 ) and collecting electrodes ( 12 ) in the form of layers of gold, and the conducting contacts ( 13 , 14 , 15 ) are made of a palladium-silver layer, whereas on the edge surfaces of the ceramic plates there are edge contacts ( 16 ), which are made of silver layer.
