In the fourth installment in our series about the history of ion chromatography development at Metrohm over the years, we now focus on some of our combined analysis techniques. These are unique combinations of Metrohm instruments from different product groups which broaden application possibilities beyond what IC could accomplish alone. The TitrIC and VoltIC systems will be discussed in this installment.
TitrIC: combining titration, direct measurement, and IC in one
The combination of titration, pH, and conductivity measurement, as well as ion chromatography in a single analytical system was introduced in the late 1990s. This TitrIC system consisted of a Titrino for the determination of the p- and m-value (alkalinity), pH and conductivity meters, as well as a modular IC from the 732 IC Detector generation.
Depending on the analysis requirements, either a second Titrino (for the Ca/Mg water hardness determination) or a second IC channel (for alkali and alkaline earth metal cations as well as ammonium) was selected. The latter enabled an automatic determination of the ion balance for the first time.
