Dear Members of the PREP Symposium Community: 

First of all, we hope that you are safe and continue to cope with the pandemic in the best possible ways. As you know, last April, the organizing committee supported by the scientific committee decided early on that it was prudent to postpone PREP2020, which had been scheduled for June 2020, to June 2021. Of course, although, at that time, it was heart-wrenching, that decision turned out to be absolutely right. Unfortunately, however, while the COVID vaccines promise light at the end of the tunnel, the current situation and lingering uncertainties still do not allow for a safe and successful in-person meeting this year. Consequently, both committees have agreed to further postpone the meeting to 2022. PREP2022 will be held on May 15-18, 2022 at the Hyatt Regency Baltimore Inner Harbor. A new call for papers will be issued in the coming months. 

In the meanwhile, a Virtual PREP2021 meeting will be held on June 7-9, 2021. While the virtual meeting will not attempt to duplicate all that the PREP Symposia have provided to our community during the last 33 years, it can still provide many benefits to the preparative and process chromatography community. This virtual meeting will provide training workshops, scientific talks, and vendor technical workshops that will help our knowledge grow, our science progress, and our technological advancements be showcased and in full display to the community. Details on the virtual meeting will be provided at a later date.

Welcome to 3 days of exciting science, technology, and education at e-PREP 2021, part of the longest running, most recognized international scientific conference and exposition driving the field of Preparative and Process Chromatography, organized by expert scientists and engineers for the separation science practitioner. Join us for a dynamic program where world renowned speakers will address in-depth the latest scientific and technological advances, critical and emerging applications and processes, and challenges and solutions in all aspects of Preparative and Process Chromatography, Ion Exchange, Adsorption/Desorption Processes and Related Separation Techniques.

The focus of this conference is the development, design, optimization, and operation of chromatographic processes and technology for a broad range of applications. The program will include papers on biochromatography, downstream processing, QbD, monoclonal antibodies, plasmids, enzymes, vaccines, viral vectors for gene delivery, VLPs, and other biopharmaceuticals, clearance of high-risk impurities such as host cell proteins, chiral molecules, SFC, fine chemicals, peptides, proteins, oligonucleotides, APIs, natural products, batch, multi-column and continuous SMB processes, column technology and equipment, monoliths, new and improved stationary phases, membrane chromatography, product quality, stability, safety and/or immunogenicity, and related process control strategies, regulatory aspects, and more!

  • Learn how to find current tools and develop practical solutions to chromatographic separations.
  • Learn how to successfully optimize chromatography processes and minimize costs for the best economic production.
  • Discuss and learn about current and future challenges and opportunities in the industry.
  • Evaluate and compare the latest products, instruments, techniques and processes that are driving the pace of innovation in Preparative and Process chromatography.
  • Interact with world leading scientists and engineers who will discuss critical and emerging areas in all aspects of Preparative and Process liquid chromatography.
