Abstract
One of the remaining challenges in providing effective preparative LC−MS purification is balancing throughput and compound purity. We describe here an approach to optimizing preparative LC−MS methods that provides significantly better chromatographic resolution and, hence, better compound purity than generic preparative LC methods consuming the same amount of time. This approach is easier to implement, is more rugged, and permits significantly greater flexibility than previously reported approaches. The instrument configurations and protocols presented here are specifically tailored for open access support, but the basic approach is equally suitable and effective in high-throughput situations.
