ABSTRACT:
A reaction cell system for measurement of catalyst demand includes a spherical chamber having an inlet with a diametrically opposed outlet. An optical cylinder traverses the spherical chamber above an agitator maintained at the bottom thereof. The optical cylinder has a slit passing therethrough adjacent a wall of the spherical cylinder such that laminar and uniform flow of fluid within the chamber passes through the slit. The valving between the inlet and outlet of the chamber is such that the inlet valve opens before and closes after similar actuation of the outlet valve. A source of catalyst and indicator communicate with diaphragm dispensers which are operative to inject precise volumes of catalyst and indicator into the spherical chamber. A valve network allows for passage of the catalyst and indicator into the chamber or into measurement standards. Additionally, the valve network communicates with the source of fluid that feeds the chamber to allow for complete and total flushing of the system.
