METHODS AND DEVICES FOR CARRYING OUT MULTIPLE SIMULTANEOUS CONDUCTOMETRIC ANALYSES

摘要

Disclosed is a device for analyzing a biological fluid comprising one or more unit cells for the conductimetric determination of an analyte in the fluid sample. Each unit cell comprises a first porous support to which biological reagents for detection of an analyte are immobilized, and a first and a second electrode spaced a fixed distance apart, wherein the porous support is adjacent to the first and second electrodes. The electrodes may be porous, with the unit cells disposed in a housing having at least one fluid flow path therein, in such a manner that fluid traversing a first fluid flow path in the housing must pass through the electrodes and the porous supports of the unit cells. Also disclosed is a method for carrying out multiple simultaneous conductimetric analyte determinations for a single sample.
