Ensuring that the product of a reaction is pure is critical to that compound’s viability as a marketable entity. Impurities often require characterization if they are in excess of regulated limits. Th...

For many chemists lab budgets, especially for consumable items, are limited. One way of trying to stretch their lab budget is to reuse disposable flash chromatography cartridges.

Flash chromatography – a purification tool for both organic chemists and natural product researchers. This tool is essential when you need to remove impurities from your targeted product, or products,...

A baseline that rises or drops when using flash chromatography with a UV detector can be a problem, especially if you are trying to collect compounds with poor detectability or that exist in low quant...

Automated flash chromatography has become an integral component of the workflows of both synthetic organic chemistry and natural product research. The most utilized chromatographic technique is normal...

Well, it’s spring as I write this, my favorite time of year, and the foliage is in various stages of bloom. I like the rebirth of nature and the floral aromas that emanate from the blooms. These botan...

Reversed-phase flash chromatography is extremely useful when purifying all types of compounds. Compounds that are charged or ionizable, however, typically need either a pH modifier (acid or base) or a...

Most chemists I meet utilizing flash chromatography use linear gradients. These gradients are either very generic (X% to Y% over a certain time or volume) or can be complex with multiple slope changes...

Flash chromatography gradients need to provide as good of a separation between the target compound at its closest eluting by-products as possible in order to maximize product purity and load. Many che...

I often get questions from customers about the influence of flow rate on their flash chromatography. Typically, the questions are…
