Matching Aromatic Solvents with Aromatic Compounds
for Flash Chromatography
February 25, 2021
As chemists we are fortunate that automated flash purification is so forgiving. The gradient nature of running the common hexane/ethyl acetate solvent system from 0 to 100% gives us many first-time successes.
Keep Silica Out of your Bump Trap: Solid Sample Loading Made Easier!
February 11, 2021
Solid sample loading is a great way to perform more efficient and consistent flash chromatography. With solid loading you can eliminate the effects of injection volume and solvent on your chromatography.
Rapidly Create Focused Gradient Methods for Prep LC from Analytical Scouting Runs
January 25, 2021
Which standard operating procedure in a preparative chromatography lab is more efficient: routinely running generic full-range gradients to purify mixtures, or taking the extra time and trouble to develop focused gradient methods?

How to Queue Up Samples to Run Automatically
January 25, 2021
One of the most popular features of the ACCQPrep, when connected to an autosampler, is the ability to create a queue of samples to be run automatically—great for walk up environments and for labs running many different samples on a regular basis, often unattended overnight.

Methods for Extending the Life of Your Prep Columns
January 22, 2021
Open-access systems provide many advantages, but an important disadvantage is the increased potential for improper column use and care. Prep labs need to be alert to the impact of injecting samples that are not properly prepared, or are dissolved in viscous solvents such as DMSO.

Back to Basics: How to Run TLC Plates Properly!
January 22, 2021
One way to more rapidly develop an optimal flash purification method is to first run the target compound using thin layer chromatography (TLC) with different mobile phase compositions.
