Claim:
1. A detector assembly configured to detect trace amounts of evaporative dissociation compounds derived from an oxidizing salt, the detector assembly comprising: a sensor assembly including a solid substrate carrying a pH sensitive molecule, an excitation source positioned to provide stimulating radiation to the pH sensitive molecule, a light sensor to monitor a response of the pH sensitive molecule to stimulation, and a heater suitable for adjusting the temperature of said sensor assembly; a sampling tip assembly in fluid communication with said sensor assembly; a heater associated with said sampling tip assembly, said heater suitable for maintaining the temperature of the sampling tip assembly at a temperature between about 90° and 350°; a gas movement pump in fluid communication with said sampling tip and said sensor assembly, said gas movement pump configured to move vapors from said sampling tip assembly to and along said solid substrate of said sensor assembly.
