EQUIPMENT FOR THE DETERMINATION OF THE ACTIVITY OR CONCENTRATION OF IONS IN SOLUTIONS |
摘要 |
<p>Measuring device for determination of the activity or of the concentration of ions in solutions, which has an electrode block having several electrodes and with a flow channel, the flow channel being in connection at its one end with a sample vessel and is connected at its other end to a line, in which a pump is interposed, with calibrating solution containers. Between the pump and the outlet of the electrode block branches off a discharge line, in which a further pump is interposed. Preferably, both pumps are combined into a peristaltic pump, the lines being laid in the segments of the pump. According to a second embodiment, the electrode block is again in connection with the calibrating solution containers. The delivery of the sample is performed however on the same side through a septum. Advantageously, the other side of the electrode block opens out into a pressure equalization vessel, into which a withdrawal line opens in which in turn the above mentioned peristaltic pump is interposed.</p> |
