Abstract
Abstract Process and device for detecting impurities in the atmosphere by an intensity-time rate technique whereby chemiluminescent reaction curves are developed and found to be representative of specific materials. Hence, by comparing known intensity-time rate curves with curves had by actual measurings, the invention enables the user to discern many more materials never before detected.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
71 words
A system for monitoring of materials in a time-intensity rate fashion comprising: an annular sample carrier system adapted to be monitored; a sample disposed in said system; monitoring means centerly located and rotatable within and in the direction of said carrier for time rate optically monitoring said sample; and means for moving said sample in said system at a rate commensurate with that of said monitoring means for time-intensity rate measurement.
Claim 2
Independent Claim
71 words
A system for monitoring of materials in a time-intensity rate fashion comprising: an annular sample carrier system adapted to be monitored; a sample disposed in said system; monitoring means centerly located and rotatable within and in the direction of said carrier for time rate optically monitoring said sample; and means for moving said sample in said system at a rate commensurate with that of said monitoring means for time-intensity rate measurement.
Claim 3
Dependent Claim
10 words
The invention of claim 1 wherein sample includes reaction chemicals.
Claim 4
Dependent Claim
20 words
The invention of claim 2 wherein said optical monitoring means includes fiber optic means for transmitting light to a photo-tube.
Claim 5
Dependent Claim
22 words
The invention of claim 3 wherein said optics are oriented to pick up light resulting from reactions in said annular carrier system.
Claim 6
Dependent Claim
16 words
The invention of claim 4 wherein said annular carrier system comprises at least one transparent tube.
Claim 7
Dependent Claim
24 words
The invention of claim 5 wherein said sample including reaction chemicals is in a fluid state and said means for moving is a pump.
Claim 8
Dependent Claim
16 words
The invention of claim 6 wherein said sample is disposed within the system by tape means.
Claim 9
Dependent Claim
54 words
A process of monitoring contaminants in the atmosphere comprising the steps of: disposing a sample of the atmosphere in a water carrier and mixing it with luminous type reactants, measuring and graphing the luminous reactions for a time frame; and comparing the graph shape with known samples to ascertain the makeup of said sample.
Claim 10
Dependent Claim
54 words
A process of monitoring contaminants in the atmosphere comprising the steps of: disposing a sample of the atmosphere in a water carrier and mixing it with luminous type reactants, measuring and graphing the luminous reactions for a time frame; and comparing the graph shape with known samples to ascertain the makeup of said sample.
Claim 11
Dependent Claim
26 words
The invention of claim 8 wherein said disposing step is by tape means and said mixing step includes material such as sodium perborate, luminol and water.
Claim 12
Dependent Claim
34 words
The invention of claim 8 wherein said measuring for a time frame is achieved by rotating a monitoring means at a rate commensurate with the rate of flow about an annular tube arranged therearound.
Claim 13
Dependent Claim
29 words
The invention of claim 10 wherein said mesuring is further made with light optics and a photo tube to facilitate the graphing which is done by an electronic recorder.
