When it comes to polar organic compound purification, many chemists turn to normal-phase flash chromatography often utilizing dichloromethane and methanol as the eluting solvents. While this can work, it often can be challenging to optimize due to methanol’s high polarity and protic chemistry.
This brochure presents the extensive range of instrumentation for flash purification from Biotage. To complement these products Biotage also offers a complete range of flash consumables, including columns in a variety of sizes packed with irregular and spherical silica, making Biotage your one-stop partner for your flash purification needs.

User Report: Isolera™ Dalton, Okayama University. The laboratory of Prof. Hiroyuki Miyachi at Okayama University installed Biotage’s Isolera Dalton, an automated mass-directed purification system for flash chromatography, allowing the fractionation and collection of optical isomers. “I felt like the world’s first mass-detection automated purification system had finally arrived.”
The term “Green Chemistry” has become a major part of the science community’s lexicon. In this application note we will look at two areas for flash chromatography: 1. Replacing chlorinated solvents with those considered more environmentally friendly. 2. Reducing solvent use and waste generation with more thoughtfully applied chromatography principles.
As reversed-phase flash chromatography gains traction in medicinal chemistry labs the need to monitor its cost and safety are becoming more important. Commonly used reversed-phase solvents typically include water with an organic solvent such as methanol or acetonitrile – each have advantages and disadvantages.
Reversed-phase chromatography is typically used when you need to separate several milligrams of relatively polar compounds that either are not soluble in normal-phase solvents or are not compatible with bare silica because they react, stick, or both. If you are currently using reversed-phase at preparative scale, such as flash chromatography, you know the mobile phase limitations – water with either methanol, acetonitrile, or THF. As with normal-phase flash chromatography, when it comes time to purify you want your crude sample fully solubilized in the weakest possible solvent at the highest possible concentration. ACS 2016
User report: Flash instruments. Chugai Pharmaceutical uses Biotage flash chromatography products for drug discovery research. When deciding to convert from manual open-column procedures to automated systems, they chose successive generations of Biotage products, ranging from the Flash+® packed column to the Biotage® Horizon, SP1, Isolera™ Spektra, and Isolera™ Dalton automated flash chromatography systems.
