Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
74 words
A composition for generating chemiluminescence comprising, in aqueous solution: (a) 10 -3 to 5 molar concentration of a water-soluble reactant which generates light by reaction with hydrogen peroxide, (b) 10 -5 to one molar concentration of a water-soluble or water dispersible organic fluorescer having spectral emission in the range about 300 to 1000 nanometers and, (c) 0.1 to 5% by wt of a surfactant, capable of producing enhanced chemiluminescence on reaction with hydrogen peroxide.
Claim 2
Dependent Claim
74 words
A composition for generating chemiluminescence comprising, in aqueous solution: (a) 10 -3 to 5 molar concentration of a water-soluble reactant which generates light by reaction with hydrogen peroxide, (b) 10 -5 to one molar concentration of a water-soluble or water dispersible organic fluorescer having spectral emission in the range about 300 to 1000 nanometers and, (c) 0.1 to 5% by wt of a surfactant, capable of producing enhanced chemiluminescence on reaction with hydrogen peroxide.
Claim 3
Dependent Claim
92 words
A dry mixture of components for making a chemiluminescent reaction by addition of the dry mixture to water, said dry mixture comprising: (a) a water-soluble reactant which generates light by reaction with hydrogen peroxide, (b) a water-soluble or water dispersible organic fluorescer having spectral emission in the range from 300 to 1000 nanometers and, (c) a surfactant, in proportions for making solution comprising the composition defined by claim 1 and (d) a solid hydrogen peroxide source selected from the group consisting of sodium perborate, potassium perborate, sodium carbonate peroxyhydrate, and histidene perhydrate.
Claim 4
Dependent Claim
13 words
A composition defined by claim 1 wherein the defined fluorescer is sulfonated rubrene.
Claim 5
Dependent Claim
13 words
A composition defined by claim 1 wherein the surfactant is a nonionic surfactant.
Claim 6
Dependent Claim
16 words
A method for producing chemiluminescence comprising dispersing a dry mixture defined by claim 2 in water.
Claim 7
Dependent Claim
25 words
A method for producing chemiluminescence comprising combining a composition defined by claim 1 with hydrogen peroxide or a source for hydrogen peroxide in aqueous solution.
