Potentiometry notes
WebPotentiometry: The plasma is diluted, acidified to convert all to CO 2, and the pCO 2 is measured with a pCO 2 electrode. Most instruments use indirect potentiometry, whereas Vitros analyzers use direct potentiometry in thin-film electrodes. These ISE methods are subject to interferences by strong redox substances (see Table 9.2 ).
