When it comes time to purify your reaction mixture or natural product extract, you have a choice to make. Should you simply load your dissolved sample onto your flash column or take the extra step to adsorb your mix onto a sorbent and dry it before loading? The choice can have a major impact on your results.
In this post, I will share results of work I conducted in my lab, comparing liquid and dry loading a reaction mixture that containing eight major components.
Are there benefits to collecting flash chromatography fractions based on multiple UV wavelengths?

UV detection and fractionation is ubiquitous in flash chromatography. It is the default methodology used to detect and collect eluting compounds. Today’s flash chromatography systems offer UV-triggered fractionation on one, two, or a range of wavelengths in order to either increase fractionation specificity, yield, or increase sensitivity.
