1. A chromatography system, comprising:

  • a chromatographic column for separating gases in a mixture from one another; and

    an electrochemical gas sensor coupled to said chromatographic column for detecting a gas;

    said electrochemical gas sensor further including;

    a substrate having a surface for depositing electrodes thereon;

    an ionomer membrane in contact with said surface and having a first outermost surface and a second outermost surface;

    an electrode in contact with said surface of said substrate; and

    an opening extending from said first outermost surface to said second outermost surface in a location proximate to said electrode for permitting a gas to diffuse through said opening to simultaneously contact said electrode and said ionomer membrane within said opening.
