TOC calibration

TOC calibration ensures the accuracy of the TOC values obtained by the analyzer. TOC
values are determined by measuring the change in conductivity of a high-purity water sample
as its organic compounds oxidize to carbon dioxide inside the analysis cell. The procedure
subtracts the average of a series of background TOC measurements from the average of a
series of user-selected standard measurements (in the form of sucrose). Linear regression is
performed on the data, and the correlation coefficient (R
are calculated and reported.
