Abstract
A multiple single use optical sensor includes a series of continuous sensor stripes deposited on a substrate web. At least one sample chamber is adapted to extend transversely across a discrete portion of the series of sensor stripes to facilitate analysis of a sample disposed therein. The sample chamber may be moved, or additional sample chambers provided to enable subsequent measurements of additional samples at unused discrete portions of the sensor stripes. The continuous nature of the sensor stripes provides consistency along the lengths thereof to enable calibration data obtained from one discrete portion of the sensor stripes to be utilized for testing an unknown sample an other discrete portion of the sensor stripes. This advantageously eliminates the need for any particular discrete portion of the sensor stripes to be contacted by more than one sample, for improved sensor performance.
