<P>PROBLEM TO BE SOLVED: To provide a calibration card and method of using the calibration card to accurately and reliably calibrate an analytical instrument capable of reading a photoluminescent oxygen probe. <P>SOLUTION: The calibration card includes at least (a) a first mass of an oxygen sensitive photoluminescent dye retained within a hermetically sealed space so as to isolate the dye from environmental oxygen, and in fluid communication with an activated metal-air battery, by which any oxygen permeating into the hermetically sealed space is quickly consumed by the battery, and (b) a second mass of an oxygen sensitive photoluminescent dye in fluid communication with the environment, by which the second mass of the photoluminescent dye is exposed to an environmental concentration of oxygen. <P>COPYRIGHT: (C)2012,JPO&INPIT |
