Welcome to 4 days of exciting science, technology, and education at PREP 2022, 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.

Special Interest Sessions

In addition to general oral and poster sessions, PREP2022 will feature special interest papers in sessions addressing critical and emerging areas in preparative chromatography including:

Industrial Case Studies in Protein Chromatography Regulatory and Data Science Perspectives in Prep Chromatography Continuous Chromatography for APIs, Fine Chemicals, and Natural Products Continuous and Integrated Processes for Biomolecules Preparative Chromatography in Drug Discovery, Development, and Manufacture


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.
