The Metrohm AG , based in Herisau is an international Swiss manufacturer of precision instruments for chemical analysis , particularly for ion analysis . In addition to the development, production and sale of its own devices, the company also develops corresponding applications that are used in a wide variety of industries.
Metrohm employs a total of around 2,000 people, around 400 of them at the Herisau site, and generates annual sales of around 350 million Swiss francs.
history
The company was founded in Herisau in 1943 by Bertold Suhner and Willi Studer . In the beginning, equipment for high-frequency and telecommunications technology was developed and produced, later precision measuring devices and radio receivers were added. The two founders, Berthold Suhner and Willi Studer, parted ways in 1947. Suhner then continued to run the company on his own. The company achieved its first significant upswing from 1947 with the first pH meters .
Metrohm AG has been a wholly-owned subsidiary of the Metrohm Foundation since 1982. In addition to running Metrohm AG, the latter is also involved in charitable and cultural purposes.
By 2006, 36 subsidiaries were founded, most of which are based abroad and form a worldwide sales network. However, both development and manufacture of the products still take place in Herisau. Today Metrohm is one of the world's leading producers of electrochemical analyzers and titration machines.
In 2011 Metrohm AG moved from its previous premises in the center of Herisau to its «Hölzli» industrial area. In 2015 the headquarters was expanded further.
Product lines
Metrohm mainly develops and sells analytical instruments for four different chemical analysis techniques:
- Ion chromatography (IC) - This method is used for the quantitative determination of ions such as sulfate, nitrate, nitrite, phosphate, chloride, fluoride, etc. (anions) in the trace range. It is less common for cations (metal ions) because atomic spectroscopic methods and voltammetry are more suitable here.
- Automated titration systems are used for the automated performance of the dimensional analysis . In itself a classic "wet chemical" method, this method is still used today to determine the water hardness and the water content in organic solvents ( Karl Fischer titration ).
- As polarography or voltammetry in general electrochemical analysis methods are referred to, in which current-voltage curves are determined. This versatile technique can be used to advantage for the determination of selected important heavy metals in environmental samples and food. Many organic analytes can also be determined in the ultra-trace range.
- Spectroscopy instruments are used as a secondary analysis method, the evaluation of which takes place very quickly and without consuming the sample material. They are based on the techniques of Raman spectroscopy and near-infrared spectroscopy and use values from the above-mentioned chemical measuring processes or other physical measuring methods as primary analytics. The use of chemometrics is essential for NIR spectroscopy .
