Abstract:
1. A method for detecting a presence of a peroxide in a gaseous medium, comprising: contacting the gaseous medium with a gravimetric sensor comprising a sensitive material, the sensitive material comprising an azaboronate having a mass which is modified on contact with the peroxide, the azaboronate corresponding to general formula (I) below: in which: m and n independently represent a whole number from 1 to 10; R R the sensor providing a first response when the peroxide is not present in the gaseous medium and providing a second response when the peroxide is present in the gaseous medium, the second response being different from the first response and corresponding to a modification of the mass of the azaboronate on contact with the peroxide; measuring a change in the response of the sensor and correlating the change of the response to the presence of the peroxide in the gaseous medium.
