Sensor calibration
First Claim
1. A method of calibrating a sensor in a sensor kit, the method comprising:
- exposing a sensing region of a sensor to a first compartment of a calibration chamber so that a first calibration solution is in contact with the sensing region;
determining the sensor output for the first calibration solution;
breaking a breakable dividing material of the calibration chamber, to form a second calibration solution comprising a mixture of the first calibration solution and a source of analyte, wherein the source of analyte is in solid form prior to breaking or removing the dividing material of the calibration chamber;
determining the sensor output for the second calibration solution; and
using the determined sensor output readings to calibrate the sensor.

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.
