In the laboratory many chemicals are used in small and larger volumes. Table 1 shows several of the typical kinds of analyses done for environmental compliance. Semivolatile organic compound extraction and evaporation can be a large source of solvent emission to the atmosphere if the solvent is allowed to go up the hood and is not recaptured.

This application note describes the use of ISOLUTE® HM-N as a support material
for pre-adsorption of a reaction mixture prior to flash chromatography. This
approach is useful when loading reaction mixtures that are only soluble in polar
solvents onto a Biotage® SNAP Ultra, SNAP KP-SIL or SNAP KP-NH column.

In this application note, we compare the amounts of a threecomponent
mixture that can be separated on columns of the
same size, 25 g, but with different Silica material: SNAP KP-Sil
(average 50 μm irregular particles), Sfär Silica (60 μm spherical
particles) and Sfär Silica HC (20 μm spherical particles) using a
Biotage® Selekt instrument.

In this study we synthesized two closely related amphipathic peptides and show the mass directed flash purification of non-acetylated ‘18A’ from a crude mixture containing a single residue deletion sequence ‘17A’ (-Glu residue) using the Biotage® Isolera Dalton™.

Here we show how flash chromatography with mass directed fractionation can be used for purifying carbohydrate derivatives such as β-D-glucosamine pentaacetate 1 as a model compound, and other UV transparent or poorly UV absorbing compounds using either normal or reversed-phase chromatography.

Developed by collaboration with the University of Eindhoven, European Regional Marketing and R+D, this application note describes the application of Isolera Dalton to the detection of multiply charged peptide ions prior to purification. This effectively increases the range of the Isolera Dalton mass detection, for this class of compounds and demonstrates that Isolera Dalton is a fully integrated purification instrument rather than a simple MS based analytical tool.

In this poster we will show how using reversed-phase flash chromatography with the new Biotage® Isolera™ Dalton mass-directed flash purification system provides real-time simultaneous separation, detection, and identification of lipids.

Mass-directed flash purification is a simple and effective
technique to detect and fractionate compounds with poor UV chromophores. In this study, fatty acid methyl ester mixtures were purified by mass-directed flash purification using the Biotage Isolera™ Dalton System.

Natural product chemistry deals with discovering the previously unknown in nature. Compounds found in nature are typically found in low quantity and thus extractions are needed to isolate certain compounds classes or at least compounds with similar solubility.
