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. Keywords: Isolera™ Dalton, Isolera™ Spektra, 10 Isolera™ Spektra One and Four, Isolera™ Spektra LS (Large Scale), Isolera™ Prime, Isolera™ ELSD-1080, Biotage® Flash 75/150, Biotage® Flash 400
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.
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.
Peptide purification using standard reversed phase HPLC methods are hampered by low loading capacity, resulting in purifications that demand significant time investment. Recently, the use of reversed phase flash chromatography has increased in popularity for peptide purification due to the significant reduction of purification time, enabled by the increased loading levels of the larger stationary phase particles. Resolution, though, is somewhat diminished with the larger particle size, demanding creative techniques to retain a highly pure peptide product.
In medicinal chemistry, organic synthesis will generate by-products with similar chemistry to the product. Separating these impurities from the product often becomes a challenge that often only prep HPLC can achieve. In this poster, we discuss how using sample dry loading with a cation exchange scavenger media with flash chromatography improves product purity by removing many of the impurities.
