Greetings and Congratulations

Congratulations on 25th anniversary, PSS!
I first learned about PSS Polymer Standards Service in Mainz from Axel Mueller nearly at the moment of PSS foundation and I have been a devoted user and admirer of all what PSS has done since that time. PSS provides the best service to polymer community, listens to what researchers need and provides high quality solutions and excellent reliable services.
Many new happy anniversaries to come, PSS!
Professor Axel Müller

University of Bayreuth, Germany
When Peter Kilz and Christoph Johann, two of my Ph.D. students, asked me what I would think about founding a company producing polymer standards and custom-made polymers I was more than skeptical. Anyway, they insisted and I remember our brainstorming for the name and the first logo of this company. Now, after 25 years of expanding in size and products, first polymer analysis software and then the corresponding hardware, they have grown from a lab in the basement of Mainz University into a multinational company in their own splendid new building. I am proud of seeing this dynamic, still young company further growing.
Happy anniversary, PSS!!
Professor Robert G Gilbert

University of Queensland, Australia
It has been 25 great years of superb service to the polymer community. The service is superb because of your scientific excellence, which leads to the highest technical competence in the market. When those who want to characterize polymers need answers that are RIGHT (which is very different from answers that might be easy to obtain but could be wrong!), PSS is where to go.
Thanks and greetings from Down Under.

25 years of PSS?? So long already?? Wöhlerstrasse seems not so long ago at all!! Time flies and we have done a lot together. Critical Chromatography, 2D-LC, high speed GPC, LC-FTIR - we have met over and over again. Hopefully it will be the same in the future; we will bridge the 10,000 km distance Mainz - Stellenbosch.
Peter, Joachim, Friedhelm, Jochen and Ralf, as well as all other employees of PSS: All the best for the next 25 years. Stay innovative and research-oriented. I am looking forward to our continued collaboration.
Professor Peter Schoenmakers

University of Amsterdam, The Netherlands
Our friends at PSS have been able to capture a gigantic amount of knowledge on polymer separations, thanks to their intensive interactions with everyone in the field.
This has made them into an invaluable source of not just products, but also information and advice.
They – and the polymer-analysis community – have many reasons to celebrate.
Professor Christopher Barner-Kowollik

Karlsruhe Institute of Technology (KIT), Germany
Whether in Australia at the University of New South Wales or at the Karlsruhe Institute of Technology (KIT): If it is about innovation all around precision-SEC, PSS is always our partner of choice. We are delighted about the excellent collaboration on variable projects, enthusiastic about the perfect service and appreciate the open minded discussions of new ideas with PSS.
Our congratulations on the 25th anniversary! We as a partner of PSS are looking forward to many coming years full of innovative PSS-typical ideas.
Professor Dhanjay Jhurry

University of Mauritius, Mauritius
We are most grateful to PSS and to Peter Kilz, in particular, for granting us a most generous offer in 2004 to purchase a size-exclusion chromatograph. We have been using the equipment on a daily basis with great satisfaction and we are most indebted to the technical staff of PSS for their immediate assistance in any troubleshooting.
Our Polymer Group extends its very best wishes to PSS as it celebrates its 25th birthday and hopes it continues to cater for the needs of the developing world.
Dr. Bastiaan Staal

BASF SE, Ludwigshafen, Germany
In behalf of “Labor Staal”, we like to congratulate PSS with their 25th anniversary. After many years of fruitful collaboration we hope to continue and strengthen this pleasant and informal relationship. We encourage PSS to keep developing new column materials, tutorials, and improving and expanding their software.
After all these years, it is hard to imagine a SEC (or GPC) laboratory without PSS columns, congratulations!
Dr. Bastiaan Staal and his laboratory technicians.

"Creative people have an insatiable need for spiritual activity, because they have found taste in the big adventures of the mind."
This citation of Hans Selye perfectly describes the founders and the employees of the PSS Polymer Standards Service GmbH. From the foundation of PSS GmbH 25 years ago until now, they have been reading the signs of time to find and bind employees who are able to do exactly the right thing at the right time and to develop what is needed.
Collaboration with PSS GmbH is pleasant because of their solid expertise, dependability, honesty, friendliness, and close relationship with the customers.
I am happy that I can personally congratulate the founders and employees of PSS GmbH on the company jubilee. My wishes for your future are success, luck, health, and the ability to successfully create and develop new ideas.
Jürgen Braun, Agilent Technologies

Channel Program Business Manager/Agilent Technologies Sales&Service GmbH&Co KG
On behalf of Agilent Technologies I want to express our congratulations to the 25th anniversary!
Since more than 10 years PSS is active as Agilent Channel Partner for complete GPC/SEC-solutions.
We appreciate very much the level of competence PSS has been able to deliver.
We do wish the entire PSS-Team a successful and prosperous future and are looking forward to a continued collaboration with Agilent Technologies.
Jens Reichenberger, Tosoh Bioscience GmbH

Product Manager GPC EMEA
This year PSS Polymer Standards Service GmbH is celebrating its 25th anniversary. This stands for 25 years of expertise and exceptional service in the field of polymer synthesis and characterization.
On this special occasion it is a great pleasure for the Tosoh Bioscience Team to thank PSS for the close collaboration. Looking forward to a successful future growth of the EcoSEC alliance, we wish PPS another 25 years of prosperous business.
Congratulation!
