Correction of Ionization Errors
: Figures 8.1-1 and 8.1-2 show the amount of
correction applied by the example program to compensate for ionization effects on
the measurements. Also shown is an ideal correction. Factors were derived by
measuring the standard solutions described in Section 2.2 with values of 0.0234,
0.07, 0.4471, 07, 1.413, 2.070, 3.920, and 7.0 mS cm
