A system of analysis, comprising means for the withdrawal of blood from a patient or other source (1) and for the conducting of the same past a measuring electrode (5) or the like and means for the feed of a diluting and/or anticoagulant fluid (13) to a point near the said source (1). The system is characterized in that the said means comprise one or more pumps (10, 14), with the help of which blood samples can be drawn intermittently, and which in between are adapted to feed some of the said fluid to the said point near the sampling point. The system is intended in particular for the measurement of potassium, calcium and sodium in the blood, but may also be used for the measurement of other substances, e g glucose in connection with diabetes. |
