4.3Detailed 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.
