  • Enhanced Purification of Capsaicins with the CombiFlash® EZ Prep

    Abstract In this application note, capsaicins are used as a model for compounds difficult to resolve with flash chromatography. Capsaicin compounds possess very similar structures making them difficult to resolve from each other. Although these compounds can be resolved on flash chromatography columns, such as the RediSep® Rf Gold C18, preparative high pressure liquid chromatography ...

  • CombiFlash Gradient Methods

    Abstract Purifying compounds require two processes: the actual purification and drying the sample afterwards. Several gradient methods were evaluated on a reaction mixture to evaluate run time and number of fractions to collect the desired compound. Reducing the volume of fractions is important to reduce the time required to dry the purified material. On large runs, drying time may be ...

  • Volumetric Analysis & Three-Dimensional Visualization of Industrial Mineral Deposits

    Abstract Base and precious metal deposits are typically characterized by a single parameter such as the total weight of mineable gold. Industrial mineral deposits, on the other hand, are characterized by their end-use. For example, the volumetric evaluation of a limestone deposit depends upon who’s buying the product. The concrete industry has a suite of evaluation parameters such as ...
