Abstract
Abstract Gaseous sample mixture and gaseous reactant mixture are brought together at one edge of a shallow disc-shaped reaction chamber. The exhaust opening of the reaction chamber is located diametrically from the mixture inlet. A light transmitting element forms one wall of the reaction chamber and the reacting gases pass through the reaction chamber in a plane substantially parallel to the light transmitting element.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
23 words
The reaction chamber of claim 1 in which the sample passage opening and the reactant passage opening are merged into a common opening.
Claim 2
Dependent Claim
26 words
The reaction chamber of claim 2 in which the axis of the sample passage forms approximately a right angle with the axis of the reactant passage.
Claim 3
Dependent Claim
26 words
The reaction chamber of claim 3 in which the common opening of the sample passage and the reactant passage has a width greater than its depth.
Claim 4
Dependent Claim
63 words
The reaction chamber of claim 4 comprising a baffle extending through said housing in a plane substantially parallel to the light transmitting element, said baffle defining the inner surface of said reaction space, said baffle having an opening located remotely from the common opening of the sample passage and the reactant passage, said opening serving as the exhaust opening for the reaction space.
Claim 5
Dependent Claim
36 words
The reaction chamber of claim 4 in which the axis of the exhaust opening is located in substantially the same plane as the axis of the common opening of the sample passage and the reactant passage.
Claim 6
Dependent Claim
34 words
The reaction chamber of claim 1 in which the axis of the exhaust opening is located in substantially the same plane as the axes of the sample passage opening and the reactant passage opening.
Claim 7
Dependent Claim
61 words
The reaction chamber of claim 1 wherein the rear wall of the reaction space comprises a baffle extending through said housing in a plane substantially parallel to the light transmitting element, said baffle having an opening located remotely from the common opening of the sample passage and the reactant passage, said opening serving as the exhaust opening for the reaction space.
