Abstract
A calibration tool for use in combination with a photoluminescent oxygen-sensitive working probe and an analytical instrument capable of reading the working probe. The calibration tool is effective for achieving two-point calibration of the analytical instrument, and includes at least first and second solid state compositions having different sensitivities to oxygen. The first composition is an oxygen-sensitive photoluminescent dye that is the same as that in the working probe, embedded within an oxygen-permeable carrier matrix that is the same as that in the working probe. The second composition is an oxygen-sensitive photoluminescent dye that is the same as that in the first composition, embedded within a carrier matrix that is different from that in the first composition. The oxygen sensitivity of the second composition is less than the oxygen sensitivity of the first composition.
