[Flow-optimized multianalytical system for haemoanalysis with ion-selective disc and coated glass electrodes...

Using theoretical models based on the low resistance coefficients of variously shaped bodies subjected to a streaming fluid, a flow-optimized multianalytical system was developed for ion-selective disc electrodes and for Na+-, K+- and Ca2+-selective coated glass electrodes. Due to the streamlined configuration of the carrier PVC membrane region, the flow is uncongested and free of dead spaces. This allows a rapid and precise measurement in serum, plasma or heparinized blood. The system was subjected to a durability test.
