When should I use dry loading instead of liquid loading with flash column chromatography?

Many microwave assisted organic synthesis (MAOS) reactions use polar solvents such as alcohols, DMF, DMSO, because they absorb and transfer microwave energy very efficiently.  However, the downside of using polar, microwave absorbing solvents is that they can interfere with the flash chromatography that follows it injected directly onto a flash cartridge.

In this post, I discuss why dry loading can be advantageous when purifying polar-solvated reaction mixtures.
