4.4 Cal
Although the instrument has been calibrated to your specifications
at the factory, it should be rechecked after satisfactory installation and
periodically calibrated as suggested for your application.
The analyzer calibration is performed by an “end-to-end” method,
whereby a known chemical standard solution is introduced to the
analyzer and the analyzer is “spanned” to that value.
4.4.1 Organic and Inorganic Carbon Standards
KHP (Potassium Hydrogen Phthalate) is recommended for the
organic carbon standard solution. Sodium Carbonate is recommended
for the inorganic carbon standard. Table 3-1 provides the concentration
to be used for two ranges of different chemical compounds (organic &
inorganic carbon). Using a ratio of these concentrations will provide
other ranges for the span solution.
