The analysis system described here combines titration, ion chromatography and direct measurement in a single analytical unit.
It has been especially developed for automated drinking water analysis but can be adapted to suit any number of analytical requirements in food, electroplating or pharmaceutical industries.
The emphasis has been placed on user-friendly operation, variable sample vessel volumes and protection of the samples from environmental interferences.
A detailed description of the setup is given as are results obtained by analysing tap water from Herisau (Switzerland) using TitrIC.
The problem.
Water contamination is widespread environmental problem.
Every year some 700 million tons of waste enter the aqueous systems and thus reduce our already limited freshwater resources.
Highly effective monitoring tools are required for assessing the occurrence, the fate, and the environmental impacts of contaminants.
Direct measurement, titration and ion chromatography are incorporated in one system.
The determination of ionic components in water samples includes direct measurements of temperature, conductivity and pH.
The acid capacity and the concentration of calcium and magnesium are determined titrimetrically.
Anions are quantified by ion chromatography.
Features.
Additional titrators can be added or existing titration methods modified.
The range of ions to be determined can easily be extended.
Different sample preparation techniques (dilution, ultrafiltration or dialysis) can be integrated.
