Abstract
Aqueous acidic ferrioxalate compositions are disclosed for use as calibrants of pCO2 and of PO2 after photodecomposition. Compositions with high iron(III) to oxalate molar ratios (e.g., 5:1 to 100:1 with 0.3 to 15 millimolar oxalate) produce carbon dioxide on exposure without oxygen consumption. Compositions with low iron(III) to oxalate ratios (e.g., 1:100 to 1:2000) with 0.1 to 5 millimolar iron(III) produce carbon dioxide on exposure with concurrent oxygen consumption. Use of the two types of compositions enables calibration values to be established with varying pCO2 values and with, respectively, high and low pO2 values.
