Anton Paar also offers cutting-edge technologies, such as Raman spectroscopy, X-ray diffraction (XRD), particle size analysis, and surface analysis. Anton Paar’s customers include most of the major beer and soft drink manufacturers worldwide, and companies active in the food, chemicals, petroleum, and pharmaceutical industries, as well as leading academic institutions. Anton Paar GmbH is part of the Anton Paar GmbH Group, which has 39 sales subsidiaries and eight producing sites.

In addition to its focus on research and development, Anton Paar’s growth is driven by strategic acquisitions. In 2007, the company acquired Dr. Kernchen GmbH near Hannover, Germany (specializing in optical metrology; now Anton Paar OptoTec). This was followed in 2012 by the acquisition of the Petrotest Group, Germany (petroleum industry measurement technology; now Anton Paar ProveTec), and in 2014 by CSM Instruments SA, Switzerland (surface analysis; now Anton Paar TriTec). In 2016, Anton Paar acquired a product line of Raman benchtop devices from BaySpec Inc. (California, USA) and licensed handheld Raman technology from SciAps Inc. (Massachusetts, USA). In 2017, the company integrated particle size analysis technology acquired from Cilas (France) into its product portfolio. Further expansion came with the acquisition of Quantachrome Instruments (USA) in February 2018 – now operating as Anton Paar QuantaTec – and AXO Dresden (Germany) in February 2019, enhancing capabilities in pore and porous material characterization and X-ray optics. Most recently, in 2023, Anton Paar acquired Brabender GmbH & Co. KG (Germany), now operating as Anton Paar TorqueTec, adding specialized solutions for characterizing kneading properties and lab-scale extrusion.
