SOPAT and its subsidiary Parsum now come under Endress+Hauser’s liquid analysis product center, based in Gerlingen, Germany. “The particle characterization systems developed by SOPAT complement our existing portfolio by adding a range that is strategically important in terms of our core target industries,” said Endress+Hauser Liquid Analysis Managing Director Dr Thomas Buer. SOPAT GmbH was founded in Berlin in 2012 by Jörn Emmerich and Dr Sebastian Maaß. In 2022, it acquired Parsum in Chemnitz, Germany, a maker of inline particle size analysis systems founded in 1997. SOPAT and its subsidiary Parsum now have a combined workforce of 30.
SOPAT’s smart systems use a photo-optical image-based inline technology to analyze particles, droplets and bubbles in running processes in real time. The technology measures particle sizes and shapes without sampling or dilution, thereby enabling precision process monitoring, faster response times and enhanced product quality. Parsum probes, on the other hand, use a laser beam in combination with fiber-optic spatial filtering to analyze particle size and particle speed distributions, particularly for solids, powders and granulates.
Improved process insights
Customers in multiple industries, including life sciences, food & beverage and mining, minerals & metals, use particle counting and analysis to ensure product quality. “This step is a continuation of our strategy and strengthens our analysis portfolio. We can now provide even better support for our customers across the board, from laboratory to production process,” Dr Thomas Buer said.
Endress+Hauser acquired SOPAT effective 1 January 2026. Both parties have agreed to keep the details of the sale confidential. Jörn Emmerich and Dr Sebastian Maaß, SOPAT’s co-founders, will stay on as members of the innovative company’s management team.
