ABSTRACT:
A diluent and a method of assaying are described, by which the ionic strength range of the liquid that is to be assayed potentiometrically, is compressed. The diluent comprises a predetermined concentration of (a) a protonated water-soluble organic amine having (i) a pKa greater than or equal to 9.3, and (ii) a hydroxyalkyl of 1 to 5 carbon atoms, bonded to the nitrogen of the amine, wherein the oxygen-to-carbon bond of the hydroxy is no more than two bonds removed from the nitrogen, and (b) an acid anion.
