The Reveleris X2 Flash Chromatography System is designed for the rapid purification of complex sampl (more)es by liquid chromatography. A flash chromatographic separation is performed using a cartridge containing a stationary phase such as 40-63µm silica and a mobile phase such as hexane: ethyl acetate (70:30) at a flow rate of 40mL/min at a moderate pressure (typically less than 100 psig). Although the resolution of flash chromatography is less than that of analytical or preparative high performance liquid chromatography (HPLC), where 2-5 µm particles are employed, the technique is extremely useful as it provides the chromatographer with the ability to separate gram size samples in a short period. In flash chromatography, as in analytical or preparative HPLC, the separation is a function of the relative interaction of the various compounds in the sample with the stationary phase and the mobile phase. Compounds with a stronger interaction with the stationary phase than with the mobile phase will be more strongly retained by the column and have a longer retention time (and vice versa). Typically, the chromatographer determines the general conditions for separation of the sample via thin layer chromatography (TLC). Although most flash chromatography separations are performed using a normal phase cartridge, a number of other stationary phases are available. The Reveleris X2 Flash Chromatography systems include a UV detector that can monitor three wavelengths simultaneously as well as an evaporative light scattering detector (ELSD). The ELSD provides the ability to monitor all non-volatile compounds in the mobile phase and allows the user to detect for compounds that do not absorb UV radiation. An additional benefit of the ELSD is the ability to employ mobile phases that absorb light at the same wavelength as the compound(s) of interest. Both detectors offer adjustable sensitivity settings to detect and collect small and large quantity of compounds. Mode of Operation: Gradient Flash Chromatographic System Solvent Delivery System: 4 Independent channels Gradient Formation: Binary Gradient with High Pressure Mixing Flow Rate: 1-200mL/min Flow Rate Accuracy: ± 3% (4-200mL/min) Maximum Pressure: 200psig Gradient accuracy (at 40mL/min): ± 1.5% Gradient precision (at 40mL/min): < 1% Sample Modes: Liquid or Solid Sample Modes Sample Loader: Sample loaders for 3g, 25g, and 60g can be employed Sample Loader Plunger: Three sizes (15mL, 75mL, and 150mL).
