A method for fabricating laminations of mica and conductive foils of particular utility in constructing apparatus for generating ions in air. A layer of mica is laminated to sheets of metallic foil using a thermoplastic adhesive. The foil is etched in order to form electrodes in a prescribed pattern. The mica-foil laminate may be appended to additional structures to interface actuating electronics, provide a heat sink, and for other purposes. The preferred bonding material is a thin film of thermoplastic organopolysiloxane adhesive.

Mica-electrode laminations for the generation of ions in air

An apparatus and method for sampling condensate from a vacuum chamber employing a positive displacement pump, a pulsation dampener having sufficient volumetric flexibility to substantially dampen the pump's pressure surge, and a pressure regulating valve. The apparatus can be used in conjunction with sodium detectors, ion exchange analyzers, conductivity cells and other contaminant monitoring devices.

Hotwell sampling system

A method is disclosed for fabricating laminations of mica and conductive foils for generation of ions in air. A layer of mica is laminated to sheets of metallic foil using pressure sensitive adhesive as the bonding material. The foil is etched in order to form electrodes in a desired pattern. The mica-foil laminate may include an encapsulating layer or tape of pressure sensitive adhesive around the edges.
