High pressure flash column
WebAug 14, 2024 · This type of HILIC gradient flash separation has yet to be utilised as a method for purification in medicinal chemistry laboratories, but is advantageous due to better theoretical sample loading than reversed phase HPLC. The Gold silica flash columns are re-useable and similar separation is achieved even after 10 injections. WebJun 5, 2012 · In a typical column (Fig. 1), the stationary phase, a solid adsorbent normally silica gel (SiO 2) or alumina (Al 2 O 3), is placed in a vertical glass column. The mobile phase, a liquid, is added to the top of the column and flows down through the column by either gravity or external pressure (flash chromatography).
