Title:
APPARATUS AND METHOD FOR ANALYTICAL DETERMINATIONS
Document Type and Number:
WIPO Patent Application WO2004015064
Kind Code:
A3
Abstract:
An apparatus and method for measuring conductance are provided. The method and apparatus are particularly well adapted for use with a removable or replaceable cartridge (10) in a blood analysis system. The apparatus generally involves providing a system having a first, unfiltered, conductance measurement cell and a second filtered, conductance measurement cell (20, 20a, 20b, 20c) and a second, filtered, conductance measurement cell (21, 21a, 21b, 21c). The preferred method involves relating values measured in the two cells for a whole blood sample and for a known calibrant together, to obtain a value, for example hematocrit, for the unknown whole blood sample.
