I have recently posted on how solvent choice influences the separation of hard to resolve compounds using normal-phase flash chromatography. As a chemist with an inquiring mind, I thought I would expand my research beyond normal-phase and see what happens in reversed-phase.
In this post, I share my results.

In this post, I will look at the impact modifying mobile phase pH can have on reversed-phase separations.

Have you ever run flash column chromatography with mass detection (Flash-MS) and observed the total ion current or TIC increase during the purification only to find that there was no discernible compound contributing to the effect?
In this post I discuss how I came across this issue and the solution I found to work.

This article discusses two recent developments in flash purification that have increased cross-over with traditional HPLC techniques: cartridge media properties and new detectors in flash systems.
