Most flash column manufacturers now offer “high performance” flash chromatography columns with the promise of higher loading, increased purity, and even reduced solvent consumption. Working for Biotage, I have made those valid claims for our products as well.
On July 26th, 2018, Bob Bickler, Senior Technical Specialist, recorded a webinar on A Roadmap to Successful Flash Chromatography. To learn more, read the description below as well as watch the recording!
For most synthesis and natural product chemists, flash chromatography is the primary tool for purification and isolation of compounds of interest. Purification methods include flash system defaulted linear gradients (e.g. 0-100%), active gradient modification (on-the-fly) during purification, and unique method creation based one either the chemist’s experience or TLC data (typically a linear gradient). Rarely do chemists work to optimize the purification to maximize target compound purity by employing a step gradient. In this post, I discuss the value optimized step gradients provide chemists.
