Abstract
A combined measuring and injecting flow cell has a single housing defining a pair of chambers connected by a small passage. The first or sensing chamber has an inlet valve and at least one monitoring member extending therein. The second or injection chamber has an outlet valve and at least one injector extending therein. Preferably at least one wall of the cell is transparent to allow visually monitoring the conditions within.
Claims20
A sample flow cell comprising:
- a housing defining a fluid tight cavity with wall means dividing said cavity into a sensing chamber and at least one injecting chamber, an opening in said wall means providing communication between said sensing and injecting chambers;
- fluid inlet means connected to said sensing chamber;
- fluid outlet means connected to each said at least one injecting chamber;
- at least one sensing means depending into said sensing chamber;
- and
- at least one injector means extending into said injecting chamber.
In a closed circuit liquid circulating system, a flow sampling cell for determining and controlling the chemical make up of the circulating liquid, said cell comprising:
- a housing defining a liquid tight cavity with wall means dividing said cavity into a sensing chamber and at least one injecting chamber, an opening in said wall means providing communication between said sensing and injecting chambers;
- fluid inlet means connected to said sensing chamber;
- fluid outlet means connected to each said at least one injecting chamber;
- at least one sensing means depending into said sensing chamber;
- and
- at least one injector means extending into each said at least one injecting chamber.
