Apparatus and associated methods relate to a one-piece structure for a solid electrolyte chemical sensor (SECS) having a first surface defining a cavity designed to receive a substrate that retains a solid electrolyte, an internal water impermeable coating on at least a portion of the first surface, a second surface that is substantially coplanar with an adjacent peripheral edge of a top surface of the substrate when the substrate is received in the cavity, and a plurality of electrical contacts disposed on the second surface adapted to electrically couple with the electrodes on the substrate when the substrate is received in the cavity and electrical paths are provided between respective electrical contacts and electrodes. In an illustrative example, the internal water impermeable coating may include a metallic material, such as gold. In various embodiments, the one-piece structure may advantageously prevent water loss from both the sensor substrate and the SECS.

An electrochemical acrylonitrile sensor comprises a housing, an electrolyte disposed within the housing, and a plurality of electrodes in contact with the electrolyte within the housing. The plurality of electrodes comprises a working electrode and a counter electrode. The electrodes comprise a catalytic material, which may comprise gold. A potential is applied between the counter electrode and the working electrode.
