HALOGEN GAS SENSOR COMPRISING COBALT

摘要

A method of halogen gas monitoring includes contacting room air to be monitored with a halogen sensor including a cobalt or cobalt alloy layer. The halogen sensor exhibits a detectable change in at least one property upon contact with a halogen gas. A measurement from the halogen sensor is obtained after the contacting. The presence of the halogen gas is monitored based on the measurement.
