Flash purification is a preparative liquid chromatography technique. As such, it incorporates the same types of components as preparative high-pressure liquid chromatography (pHPLC) – pump, gradient m...
The challenges organic, medicinal, and natural product chemists face are many: from designing reactions, to optimizing synthesis, work-up / extraction, and purification / isolation of the desired comp...
The products of organic synthesis are designed with specific functional groups in order to possess desired properties. Depending on the compound’s functionality, it can be neutral, acidic, or basic as...
Chromatography is a common tool of the chemistry laboratory, and most chemists involved in synthesis have a good idea how automated flash purification system work on the lab bench. However, knowing ho...
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 compo...
For many chemists using generic linear gradients and even gradients based on TLC the purification results often are not selective enough to separate all of the compounds in their mix. This is especial...
Recently, I posted an article explaining why high performance TLC plates are not needed for method development for high-performance flash chromatography. Based on some excellent feedback, I see a need...
The Biotage® Selekt Flash purification system is designed for the rapid and simple isolation of target molecules from complex mixtures. Typically, this is seen in the area of drug discovery, where lar...
Sometimes we find ourselves having to make decisions fast, and act even faster - especially in situations like the one we live in today, where there is a high degree of uncertainty. In this kind of si...
In drug discovery, microwaves are common tools for heating reactions to high temperatures and pressures so that it is possible to synthesize compounds in minutes that might otherwise take hours by con...
