ANALYSIS

Method:            The ADI2016HD Titro Analyzer performs a titration with Hydrochloric acid for      quick, simple and accurate analysis of small amounts of Sodium hydroxide.

Principle:          After sampling a titration is performed with Hydrochloric acid up to the ferst inflection point. Titre solution is added beyond the equivalence point. The inflection point is detected automatically by recording the change of pH/mV signal in relation with the dosed amount of Hydrochloric acid. As indication of this pH/mV change, a pH glass electrode is used.

                        The obtained result — dosed amount titre solution — is used for the determination of Sodium hydroxide according to the following calculation:

                        Concentration NaOH (g/l) = (V _HCI * t _HCl / V _Sample ) * Mw NaOH * x

                     With:       V _HCl =        dosed volume (ml) titre solution, obtained by registering the change of pH/mV in function of the amount of Hydrochloric acid added during titration

                                    t _HCl =         strength titre solution (M)

                                    V _Sample =   volume (ml) Sample device

                                    X =            e.g. density, inversion g/l > mg/l
