4.3 Detailed Calibration Procedures
1. 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.
2. Instrument calibration is performed by an “end-to-end”
method, whereby a known organic carbon chemical
standard solution is introduced to the analyzer and the
analyzer is “spanned” to that value.
3. Organic and Inorganic Carbon Standards:
a. (Potassium Hydrogen Phthalate) is recommended for
the organic carbon standard solution.
b. Sodium Carbonate is recommended for the inorganic
carbon standard.
c. Table 4-1 provides the concentration to be used for
two ranges of different chemical compounds (organic
& inorganic carbon).
d. Ratioing of these concentrations will provide other
ranges for the span solution.
