Sensor calibration
First Claim
1. A sensor kit comprising:
- (i) a sensor for detecting an analyte, said sensor having a sensing region comprising a receptor for said analyte;
(ii) a sensor housing containing said sensor, at least a part of said sensor housing being penetrable by water or aqueous solutions; and
(iii) a calibration chamber, said calibration chamber comprising at least a first and a second compartment, the first compartment containing a first calibration solution comprising water or an aqueous solution and the second compartment containing a source of said analyte, said first and second compartments being separated by a water-impermeable dividing material, wherein the dividing material comprises a breakable or removable section configured such that on breakage or removal of the section contents of the first and second compartments are mixed.

Abstract
A sensor kit comprising a sensor for detecting an analyte, a sensor housing and a calibration chamber. The calibration chamber comprises a first compartment containing a first calibration solution and a second compartment containing a source of the analyte to be detected. A dividing material is located between the first and second compartments enabling them to be mixed on breakage or removal of the dividing material. Further compartment(s) containing further source(s) of the analyte may optionally be provided. Calibration can carried out by (a) taking a reading of the analyte concentration of the first calibration solution, (b) mixing the contents of the first and second compartments by breaking or removing the dividing material, and (c) taking a reading of the analyte concentration of the resulting mixture. Steps (b) and (c) can be repeated for further compartment(s) to provide further reading(s) if desired.

20. A method of calibrating a sensor in a sensor kit, wherein said sensor kit comprises:
-
(a) said sensor for detecting an analyte, said sensor having a sensing region comprising a receptor for said analyte, (b) a sensor housing containing said sensor, at least a part of said sensor housing being penetrable by water or aqueous solutions, and (c) a calibration chamber, said calibration chamber comprising at least a first and a second compartment, the first compartment containing a first calibration solution comprising water or an aqueous solution and the second compartment containing a source of said analyte, said first and second compartments being separated by a water-impermeable dividing material, the method comprising; (i) optionally exposing the sensing region of the sensor to the first compartment of the calibration chamber so that the first calibration solution is in contact with the sensing region, (i) determining the sensor output for the first calibration solution; (ii) breaking or removing the dividing material of the calibration chamber, to form a second calibration solution comprising a mixture of the first calibration solution and the source of analyte; (iii) determining the sensor output for the second calibration solution; and (iv) using the determined sensor output readings to calibrate the sensor. - View Dependent Claims (21, 22, 23, 24)
