HPLC Method Development
1 Day
For the experienced chromatographer, this course provides a comprehensive, process-driven approach to the development of an optimal and robust HPLC method.
The course includes a detailed exploration of each critical parameter within a typical method, then builds this into step-by-step process for method development. We apply relevant theory to underpin a practical approach which maps out the optimal route to a commercial quality method. Importantly we look at building robustness into each stage of development using a Quality by Design approach, highlighting many common problems and how we develop these out.
