PSS employs the latest findings in polymer science for the synthesis and characterization of polymers, block copolymers and biopolymers. PSS operates manufacturing facility equipped with a complete state-of-the-art characterization laboratory at the headquarters in Mainz (Germany), fully supporting customers working under stringent requirements i.e., GLP, DIN, ISO 9000x certifications. 


Industry Cooperation
PSS works closely with other product manufacturers such as Agilent, Brookhaven, WGE, among others, integrating the products necessary to place at your service the most comprehensive Gel Permeation Chromatography re-solutions. PSS also works closely with important Universities and Research Institutes

PSS GmbH was founded in 1985 by 2 PhD students at the Physical Chemistry Department, University of Mainz, producing polymer standards at the University facilities. The following four years PSS expanded staff and products including tailor-made polymers, organic and aqueous GPC columns, GPC software and moved to own facilities located in a Mainz suburb. To date, PSS has successfully gained leadership in the overall GPC Market, making innovative contributions not only in Germany, but around the world, The following few examples illustrate PSS' claim of leadership: the introduction of 2-dimensional chromatography technique with dramatically improved resolution and separation efficiency; the development of WinGPC Unity into the most advanced Macromolecular Chromatography data system; a history of sustained quality manufacturing standards and columns and the excellent laboratory where the biggest challenges of macromolecular analysis are faced daily, to keep the analytical services growing at a rate of 20% per annum.

PSS-USA opened its office in Houston, Texas in 1994; moved to Silver Spring, Maryland, in 1995. From 2003 until 2011, PSS USA operated from Warwick, Rhode Island. Since November 2011, the USA headquarters has moved to its largest facility in Amherst, Massachusetts.

To continue leading the advancement of Macromolecular Chromatography providing innovative analytical tools and services, and bridging any gaps you encounter in the pursuit of macromolecular understanding. 

 To continue being a reliable source of high quality products and services, using state of the art equipment and applying the latest findings in polymer and materials science.

Research, Design and Innovation
