AQUEOUS BICARBONATE SOLUTIONS WHEN EQUILIBRATED WITH GIVEN CONCENTRATIONS OF CARBON DIOXIDE-CONTAINING GASES WILL EXHIBIT A PREDETERMINABLE PH BEHAVIOR. BY PRESELECTION OF BICARBONATE CONCENTRATION AND EQUILIBRATION GAS COMPOSITIONS, LIQUID CALIBRATION FLUIDS SUITABLE TO STANDARDIZED INSTRUMENTS, E.G., BLOOD MEASURING DEVICES, MAY BE PREPARED HAVING GIVEN PH CONCENTRATIONS AND PARTIAL PRESSURES OF CARBON DIOXIDE AND OTHER GASES E.G., OXYGEN. |
