Portable Liquid Chromatography Platform for Diverse Pharmaceutical Applications

点击翻译按钮获取中文摘要

Project Summary Liquid chromatography (LC) is the most important analytical technique in the pharmaceutical industry. Currently available LC instruments on the market suffer from high cost and large size, contrary to the general trend of miniaturization within the field of analytical instrumentation. Axcend Corporation has developed a compact LC platform weighing 7 kg while still maintaining similar performance to the more traditional LC models. In this Fast-Track SBIR project, researchers at Axcend Corporation in collaboration with capillary LC instrumentation experts at Rowan University, two LC column manufacturers, and several leading international pharmaceutical manufacturers, will adapt this compact LC instrument to fulfill the needs in the pharmaceutical industry. In Phase I, the capability of the instrument to meet regulatory guidelines in terms of chromatographic performance and data auditing will be demonstrated. Once completed, Phase II will involve the use of the system in a number of relevant pharmaceutical applications. A high-throughput gradient LC screening method will be developed to identify impurities in new chemical entities. The system will also be coupled to both batch and process manufacturing streams for on-line reaction monitoring in real-time. New capillary LC columns will be developed to enhance the separation of protein-based therapeutics (antibody-drug conjugates, or ADCs) and then applied to the full workflow required to characterize these ADCs. All of these aims will be achieved by using the Axcend compact LC system, which is smaller, has a lower cost, is simpler to use, and reduces solvent waste over 1,000-fold over traditional LC methodology.
