Abstract
A flow-through cell has a body under which an ion-selective electrode is disposed. The side portion of the cell body is provided with a reference electrode. The cell body has a sample path with a crank form and also has a substantially horizontally extended path for a reference electrode solution. The crank path has a lower horizontal part, so that it is possible to suppress the undesirable flowing down of the reference electrode solution into the ion-selective electrode during an ion concentration measurement operation. The crank path has a upper horizontal part, which serve to suppress the undesirable flowing of the blood cells contained in the blood sample towards the path for the reference electrode solution. Furthermore, the crank path for the sample is designed to suppress the occurrence of bubbles in the path, with the previso that, if such bubbles should occur, these bubbles may be smoothly withdrawn.
