Abstract
Abstract A main measuring path and an auxiliary path individually extend from a common junction at the input of a polarographic analyzer to separate output ports thereof. A vane defining a common wall between the two paths cooperates with a transversely disposed baffle member located upstream of a vane to direct a relatively small, substantially constant portion of the total input flow toward the main path, thereby permitting efficient liquid separation at the output of the main path. The remainder of the input flow is directed through the auxiliary path.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
125 words
In a polarographic analyzer having an input port into which a test liquid may be introduced, a first output port, and a first flow path between the input port and the first output port, an arrangement for maintaining the flow of the test liquid in the first path at a substantially constant level, which comprises: a second output port; means defining a second flow path between the input port and the second output port with the first and second paths intersecting at a first junction; and means for dividing the flow of test liquid entering the input port between the first and second paths such that incremental increases in the flow of the test liquid through the input port are directed into the second path.
Claim 2
Dependent Claim
125 words

Claim 3
Dependent Claim
98 words
An analyzer as defined in claim 1, in which the dividing means comprises, in combination, a vane defining a common wall of the first and second paths and extending from the junction toward the input port, the vane being oriented to establish a relatively small opening between the input port and the first path and a relatively large opening between the inpuT port and the second path; and a baffle member located between the input port and the vane and disposed transversely to the flow of the test liquid for diverting such flow toward said relatively large opening.
Claim 4
Dependent Claim
44 words
An analyzer as defined in claim 2, in which the analyzer further comprises means for introducing mercury into the first path, and in which the first output port includes a first liquid closure for preventing the joint outflow therethrough of mercury and test liquid.
Claim 5
Dependent Claim
33 words
An analyzer as defined in claim 3, in which the analyzer further comprises a third output port including a second liquid closure for preventing the joint outflow therethrough of mercury and test liquid.
