Flow-through cell provided with reference electrode

A flow-through cell provided with a reference electrode, comprising:

• a cell body, having a sample path extending therethrough from a lower surface of the cell at an inlet to an upper surface of the cell at an outlet, the sample path having a crank path configuration including an upper horizontal part, a lower horizontal part, a first vertical part that communicates with each of said upper and lower horizontal parts, a second vertical part that communicates with the inlet and the lower horizontal part;
• and a third vertical part that communicates with the upper horizontal part and the outlet;
• a reference electrode directly connected to a side of the cell body, the cell body having a path for a reference electrode solution, and said reference electrode having a bore wherein the path of the reference electrode solution is coaxially disposed with respect to the bore at one end thereof and is open at a middle portion of the first vertical part of the crank path at the other end, and further wherein the path for the reference electrode solution extends substantially horizontally through the cell body;
• means for pumping disposed downstream of the cell body outlet for withdrawing liquid from the cell body through the outlet;
• and an ion-selective electrode directly connected to the lower surface of the cell body at the inlet.
