    • Process for detecting a gaseous compound of BX3, HX or X2 type within a gas using a composition containing a probe molecule, characterized in that the probe molecule is a molecule for which the reaction with one or more compounds of BX3, HX or X2 type leads to a variation of at least one of its physicochemical properties, this variation being measurable via a suitable analysis technique, and in that the following steps are carried out in this order: (a) measurement of said physicochemical property of the probe molecule, such as a spectral property, (b) bringing the gas into contact with the composition containing the probe molecule from step (a), (c) repeat measurement of said physicochemical property, (d) correlation of the variation of said spectral property between steps (a) and (c) in the presence of said gaseous compound of BX3, HX or X2 type, wherein the measurement of the physicochemical property from step (a) is possibly a prior step, process for trapping gaseous compounds of BX3, HX or X2 type contained in a gas, material capable of reacting with at least one compound of BX3, HX or X2 type in gaseous form and sensor for compounds of BX3, HX or X2 type.

    • 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.
    • 一种气体检测保险丝,其包括导电材料(例如金属)的薄条或片,连接用于检测感兴趣的气体的两个电极。 选择金属与感兴趣的气体反应,并且具有相当大的表面积,使得当感兴趣的气体接触金属时,电极之间的电连接被破坏(例如,由于金属损失物理完整性 ,或由于与气体的反应而变得不导电)。 感兴趣的气体可以是氯,并且导电材料可以是锡。 当锡暴露于氯时,锡变得氧化,产生四氯化锡液体,从而破坏电气连接。
