On September 4, 2003, Suslick, Kenneth S. published a patent.Name: 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride The title of the patent was Colorimetric artificial nose having an array of dyes and method for artificial olfaction. And the patent contained the following:
The present invention involves an artificial nose comprising an array, the array comprising at least a 1st dye and a 2nd dye deposited directly onto a single support in a predetermined pattern combination, the combination of dyes in the array having a distinct and direct spectral absorbance or reflectance response to distinct analytes comprising one or more parent analytes or their derivatives In one embodiment, the invention further comprises an oxidizing source to partially oxidize at least one distinct parent analyte to at least one corresponding derivative analyte of said parent analyte, the array at least in part having a stronger distinct and direct absorbance or reflectance response to the derivative analyte than to the corresponding parent analyte. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Name: 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride
The Article related to colorimetric artificial nose array dye olfaction, Organic Analytical Chemistry: Apparatus and other aspects.Name: 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride
