Abstract
A gas detection fuse comprising a thin strip or sheet of a conductive material, such as a metal, connecting two electrodes for detecting a gas of interest. The metal is selected to be reactive with the gas of interest, and has a relatively large surface area, such that when the gas of interest contacts the metal, the electrical connection between the electrodes is broken (e.g., due to the metal losing physical integrity, or becoming non-conductive, as a result of the reaction with the gas). The gas of interest may be chlorine, and the conducting material may be tin. When the tin is exposed to chlorine the tin becomes oxidized to produce liquid tin tetrachloride, thus breaking the electrical connection.
Claims9
An apparatus comprising:
- a total organic carbon (TOC) analyzer having an exhaust that outputs gaseous analysis byproducts;
- a pair of electrodes;
- a connecting member comprising conducting material providing an electrical connection between the pair of electrodes and positioned to contact the gaseous analysis byproducts, the connecting member reactive with one of more of the gaseous analysis byproducts such that reaction of one or more of the gaseous analysis byproducts with the connecting member breaks the electrical connection between the pair of electrodes;
- and
- a controller connected to at least one of the pair of electrodes and configured to generate a gas warning output and/or shut down the TOC analyzer in response to determining that the electrical connection between the pair of electrodes is broken.
