Welcome to the Biotage Flash Purification Blogs.

      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. In this post, I will discuss the value of incorporating fractionation based on a wavelength range and two selectable individual wavelengths.
