Water is a necessity of life for all organisms—no life is possible without water! Water is required as a solvent and as a transport and swelling agent—in this way it makes a wide range of different chemical and colloidal cell reactions possible.

We all need pure, healthy and unpolluted water. Maintaining its purity is not just the responsibility of the environmental or the water supply and distribution authorities, every one of us is concerned.

As a result there is a wide range of very different regulations and directives throughout the world from which an independent analytical branch has developed.

The aim of this monograph is to show which parameters/water constituents can be analyzed with Metrohm instruments.

797 VA Computrace

Metrohm AG

The versatile instrument for voltammetry 797 VA Computrace is a modern voltammetric work station connected to the PC via a USB port. The complementary PC software controls the determination, records and evaluates the measured data. Thanks to the sophisticated program design the operation is unbeatably simple. All the methods that are described in the Metrohm Application Bulletins and Metrohm Application Notes are already preinstalled. The integrated new designed potentiostat with galvanostat guarantees highest precision with reduced noise. The well-proven Multi Mode Electrode (MME) as well as rotating disk electrodes (RDE) from different materials are available as working electrodes, of course. The most important applications Stripping Voltammetry: Voltammetric trace analysis of metal ions and other substances CVS: Cyclic Voltammetric Stripping for the determination or additives in plating solutions Exploratory: The Metrohm concept for teaching in electrochemistry

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors.

Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis.

In a voltammeter the current is measured in the system whilst the voltage is varied. Usually 3 metal electrodes are required including the reference, auxiliary and working electrodes. In polarography, a subclass of voltammetry, the working electrode used is a dropping mercury electrode (DME). The 2 main types of voltammetry are cyclic and linear sweep voltammetry.pH and Conductivity MetersIon and pH meters, used for electrochemical techniques and measurements, measure the concentration of specific ions using electrodes (probes) and a meter. Features of ph and ion meters to consider include temperature compensation, auto-calibration, adjustable resolution, measurable range and accuracy. Meters can be handheld, portable, benchtop and modular.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.
