Investigation of different column packing methods on the efficiency of chromatographic separation for biotechnology and pharmaceutical applications

反相液相色谱是生物制药工业中生物化合物纯化的主要下游操作。填充床色谱柱对色谱步骤的性能至关重要。随着新的色谱柱填充方法的开发，有必要对色谱柱进行鉴定，以确保它们以稳健和一致的方式运行。此外，随着新的分析方法和制备规模方法的开发，需要改进柱填充方法或修改当前方法。在过去的几年里，该应用的工业合作伙伴PolyAnalytik Inc.参与了制药和医疗器械行业的多个研发项目。 PolyAnalytik Inc.十年来，他也一直从事销售色谱柱，用于分离小分子和大分子。 该组织在制药应用中使用的纯化和色谱技术方面获得的广泛知识和经验使该组织能够考虑开发含有生物处理树脂的独特包装色谱柱，用于许多纯化应用（例如，用于蛋白质，肽，抗病毒等药物）。 PolyAnalytik Inc.拥有几种专有的色谱柱填充方法。在该提案中，Bassi实验室将探索实验和数学建模工具，与Polyanalytik合作研究这些色谱柱的填充柱效率，以进一步推进高效系统的开发。这项与UWO的Bassi实验室合作进行的关于柱填充效率的调查研究对Polyanalytik至关重要，因为这种填充柱的开发将导致创新和独特的填充柱用于高效色谱应用。

Preparative liquid chromatography is the dominant, downstream operation for the purification ofbiological compounds in the bio-pharmaceutical industries. The packed bed column is essential to the performance of the chromatographic step. As new column packing methods are developed, it is necessary to qualify columns to ensure they perform in a robust and consistent fashion. In addition, as new analytical procedures and preparative scale approaches are developed, improved methods are needed for column packing or modifications to current approaches are required. Over the past few years, the industrial partner in this application, PolyAnalytik Inc., has been a part of several research and development projects (R&D) in the pharmaceutical and medical device industries. PolyAnalytik Inc. has also been involved in selling chromatographic columns in the separation of small molecules and macromolecules for a decade. The extensive knowledge and experience gained by the organization in the purification and chromatographic techniques used in pharmaceuticals applications have allowed the organization to consider the development of uniquely packed chromatographic columns containing bioprocessing resins for many purification applications (e.g. for pharmaceuticals such as proteins, peptides, antiviruses). PolyAnalytik Inc. owns several proprietary approaches for column packing. In this proposal, the Bassi lab will explore experimental and mathematical modelling tools to investigate the packed column efficiency of these columns in collaboration with Polyanalytik to further advance the development of highly efficient systems. This investigative study on column packing efficiencies in partnership with the Bassi laboratory at UWO is crucial to Polyanalytik as the development of such packed columns as this will lead to innovative and distinctively packed columns for high efficiency chromatographic applications.
