Title:
SYSTEMS AND METHODS FOR CALIBRATING OSMOLARITY MEASURING DEVICES
Document Type and Number:
WIPO Patent Application WO2005076796
Kind Code:
A3
Abstract:
An osmolarity measuring system comprising micro scale electrode arrays is configured to account for variations and defects in the arrays using a tiered approach comprising several calibration methods. One method accounts for the intrinsic conductivity of the electrodes and subtracts out the intrinsic conductivity on a pair-wise basis, when determining osmolarity of a sample fluid. Other methods in the tiered approach use standards to determine calibration factors for the electrodes that can then be used to adjust subsequent osmolarity measurements for a sample fluid. The use of a standard can also be combined with a washing step.
