VORRICHTUNG ZUR BESTIMMUNG DES HAEMATOKRIT

摘要

There is described a method and apparatus for the determination of hematocrit levels in which both the conductivity of whole blood and the conductivity of blood plasma are determined together. While a conductivity cell (18) is being used for the determination of the conductivity of whole blood, the conductivity of plasma is calculated in a computer (30) with the aid of ion selective electrodes (14, 16) from the sodium or potassium concentrations.
