Summary

A Na+-selective PVC-membrane electrode which allows continuous measurement of Na+-activities in undiluted urine samples is described. In view of routine clinical analysis and bedside monitoring in intensive care units a miniaturized electrode system has been developed. When the Na+-concentrations determined by ion selective electrodes are correlated with those obtained for the same samples via flame photometry and atomic absorption, the residual standard deviation is found to be ±4.5 mM over the 50 to 250 mM Na+ range.

Zusammenfassung

Eine Na+-selektive PVC-Membranelektrode wurde beschrieben, die die Bestimmung der Na+-Aktivität in unverdünnten Urinproben ermöglicht. Im Hinblick auf klinische Routineuntersuchungen sowie den Einsatz in Intensivstationen wurde ein miniaturisiertes Elektrodensystem entwickelt. Die Korrelation der mit ionenselektiven Elektroden ermittelten Meßwerte mit Ergebnissen der Flammenphotometrie und der Atomabsorptionsspektrometrie ergibt eine Standardabweichung um die Regressionsgerade von ±4,5 mM über den Na+-Konzentrationsbereich von 50÷250 mM.
