7.8. Titration table
In the Vapodest system a pH-end point determination for the detection of the
measuring value. The functions in the titration table have an inuence on the titra-
tion speed. The lower the N-content of the sample the more careful the additional
amount of titration solution has to be set. The concentration of the boric acid used
is an additional inuence factor. Depending on the method, you have to test seve-
ral functions, to obtain optimal results. Please check the three sample tables for
various boric acid concentrations which are located at the end of this chapter.
7.8.1. Set titration table
