1. equipment that is used to analyze the multicomponent gas potpourri comprises:

  • (a) array of four kinds or more kinds of chemistry/electricity-active material, when under selected temperature, being exposed to admixture of gas, every kind of chemistry/electricity-active material show from other chemistry/electricity-active material in each different electrical response characteristics;

    Wherein should chemistry/electricity-active material be selected from (i) and comprise M 1O xAt least a chemistry/electricity-active material and (ii) each self-contained M 1aM 2bO xAt least three kinds of chemistry/electricity-active material;

    M wherein 1Be selected from Al, Ce, Cr, Cu, Fe, Ga, Mn, Nb, Nd, Ni, Pr, Sb, Sn, Ta, Ti, W and Zn;

    M wherein 2Be selected from Ga, La, Mn, Ni, Sn, Sr, Ti, W, Y, Zn;

    M wherein 1And M 2At M 1aM 2bO xIn be separately different;

    Wherein a, b and c are about 0.0005 to about 1 independently of one another;

    WithWherein x be enough to make the oxygen of existence can equilibrium chemistry/electricity-active material in the number of electric charge of other element;

    With(b) for the device of when this array is exposed to admixture of gas, measuring every kind of chemistry/electricity-active material electroresponse.
