Abstract:
1. A method for determining the presence of an oxidizing salt comprising: collecting the oxidizing salt with a sampling material; presenting the sampling material to a sensor assembly, said sensor assembly including a solid substrate carrying a pH sensitive molecule, the pH sensitive molecule undergoing stimulation by an excitation source, said excitation source emitting light radiation at wavelengths between about 325 nm and about 700 nm, while monitoring the response of the pH sensitive molecule to the stimulation with a light sensor suitable for detecting changes in response intensity; heating the sampling material to a temperature sufficient to induce evaporative dissociation of the oxidizing salt thereby yielding evaporative dissociation compounds of the oxidizing salt; passing the evaporative dissociation compounds of the oxidizing salt into said sensor assembly and reacting said pH sensitive molecule with at least one dissociation compound; monitoring said pH sensitive molecule with said light sensor to determine any change in response intensity wherein a change in response intensity indicates the presence of oxidizing salt.
