Controller Platform For Liquid Analysis

The customer’s challenge

Metrohm Applikon needed to develop a new controller platform for their liquid process analysers; the current platform needed to be redesigned due to end-of-life problems with hardware components. The new platform had to be compatible with a range of products and be operational within a very short timeframe.

Sioux's contribution

A Sioux SWAT team, consisting of an experienced embedded architect and a software engineer, worked together with the Metrohm team to define the new platform based on functional and non-functional requirements. The choices made were quickly validated by the software engineer on a commercial prototype board.


Metrohm has shortened their time to market and mitigated technology risks with the help of Sioux. Design choices were validated at a very early stage, and the development of the new platform has quickly come up to speed, thus lowering the risk of delays.
