Latest Patents

Tuchan’s listed patent is titled “Control Arrangement for Controlling a Piston Pump Unit for Liquid Chromatography.” It describes a control arrangement for a pump with at least two piston-cylinder units that operate cyclically with offset phases to deliver a predetermined liquid flow.

The arrangement records pressure in the cylinder volume of at least one piston-cylinder unit. During a specified measurement phase, it temporarily stops that unit’s drive and records pressure data over time. This approach is designed to characterize pressure behavior while the pump operates, including under varying fluid-load resistance.

Career Highlights

The patent connects Tuchan’s work with Dionex Softron GmbH and the development of pump-control technology for liquid chromatography, including high-performance liquid chromatography. The described system focuses on measuring pressure during compression or decompression phases.

Collaborations

Gervin Ruegenberg and Richard Schloderer are identified as Tuchan’s coworkers. The available information does not specify their roles in the patent or whether they collaborated directly on it.

Conclusion

Werner Tuchan’s listed invention addresses pressure measurement and control in cyclic piston pumps for liquid chromatography, reflecting a focused contribution to analytical instrumentation.
