Patent Images
1. A calibrator for calibrating a sensor, comprising:
- a calibration chamber for containing a calibration liquid, said liquid comprising water or an aqueous solution;
an H2O2-quenching material, exposed to an interior of the calibration chamber, for contacting the calibration liquid; and
a lead screw of a mechanism for changing the concentration of an analyte in the calibration liquid, and wherein the H2O2-quenching material is a coating on the lead screw.

Abstract
A calibrator, for calibrating a sensor, has a calibration chamber for containing a calibration liquid. The liquid comprises water or an aqueous solution of an analyte to be sensed. A hydrogen peroxide-quenching material is provided exposed to the interior of the calibration chamber. The hydrogen peroxide-quenching material contacts the calibration liquid. After the calibration chamber containing the calibration liquid is sterilized by irradiation with gamma radiation, the hydrogen peroxide-quenching material decomposes any hydrogen peroxide formed in the calibration liquid to avoid adverse effects on a sensor placed in contact with the calibration liquid.
