Parsum GmbH, founded in 1997, is a member of the SOPAT Group in Germany, with headquarters in Chemnitz. The company focuses on the development and application of in-line particle measurement technology.

Parsum’s core products are particle probes based on a patented spatial-filtering principle. The product portfolio includes the IPP 80-P for pharmaceutical processes, the IPP 70-S for general applications, the IPP 70-Se for explosion-protected environments, and the IPP 75-S, which is designed for high-shear mixing systems. In addition, Parsum supplies complementary components such as the Disperser for on-line dispersion, cleaning units, and measurement software that can be configured to meet specific process requirements.

Parsum instruments are applied in pharmaceutical processes such as roller compaction, fluid-bed granulation, extrusion, milling, and pellet coating. They have been adopted by multiple companies for process monitoring and quality control purposes.
