With the motto „Nearly a nanoparticle that evades us“ the Particle Metrix GmbH has made a name for itself in recent years as an analyzer manufacturer for nanoparticles in liquids. The products are on the one hand colloid analyzers and, on the other hand equipment for clinical research and bioscience. Colloid and Life Science were established as two different companies at the end of 2017, the Colloid Metrix GmbH and the Particle Metrix GmbH. Focusing on two areas of applications, technically in the Colloid Metrix and for life science the Particle Metrix, the founders, Margret Böck and Dr. Hanno Wachernig, set a clear signal both inwards and outwards. Here innovations have matured, which offer a high level of customer benefit in the respective area and therefore deserve increased attention. We stay with the profile of Particle Metrix.

The company headquarter of Particle Metrix is located in Meerbusch near Dusseldorf, whereas production and development resides in Inning near Munich. Customers have at their disposal a competent team of chemists, physicists, biologists and engineers. It focuses on Nanoparticle Tracking Analysis (NTA) as a method for rapid and comprehensive characterization of extracellular vesicles (EVs), viruses and similar small biological particles. Our ZetaView® NTA devices provide complementary information on flow cytometry (FC) but in the lower nanometer range. The overlap of FC and NTA is typically between 100 nm and 300 nm.

Particle concentration, size distribution and surface charge are main outcome parameters for the NTA, which are available in both the scattered light and in the fluorescent light mode “F-NTA”.

Significant progress has been achieved in phenotyping with F-NTA. The ZetaView® QUATT provides the hard- and software to conveniently switch between four fluorescence channels. For upgrading possibilities from one (PMX-120) to two (PMX-220) and to four lasers, (PMX-420)  please contact → sales.



The ZetaView® is installed in the best laboratories in the world and is enjoying a growing popularity. This is largely due to our employees and distributors, who keep their eyes and ears open in order to meet the customers´ wishes. Through collaborations with research institutes, Particle Metrix is increasingly working on new applications. They are our future. The standardization of processes and analyzes will also progress rapidly over the next years. A robust design and partial automation contributes to the safe and yet fast analysis. Demand for GMP, IQ/OQ/PQ and CFR 21 Part 11 continues to increase.

The measurement principle complies with the following standards: ISO 13099 - Electrophoresis, ISO 19430: 2016 (E) – PTA Particle Tracking Analysis and ASTM-E 2834-12 – NTA Nanoparticle Tracking Analysis.


We thank our cooperation partners and funding agencies (see our partners) for their confidence and we hope that new applications will always arise for our customers with the resulting insights.
