This work is an evaluation of the practicability of such a bubble column as a chromatographic device. As a

  • Why is it important to avoid air bubbles in the column ...

    Mar 17, 2009  Air bubbles represent gaps in the solid phase where no solid phase is present. Therefore, as a compound or a mixture of compounds passes through a column, their rate of elution will in effect 'speed up' at the site of an air bubble since no solid support exists.

    Note that the larger the column diameter, the more difficult it is for bubbles to pass out of the column. Therefore, if a preparative column is attached to the HPLC system, install the column so the inlet is as high as possible and the outlet as low as possible to minimize the bubbles

    Before shutting off the pump, switch to 100% methanol (MeOH) or acetonitrile (ACN) – because of their low viscosity these solvents will help to remove any air bubbles from the column. The next step is to clear any air from the column. Re-connect the column inlet, but do not connect the column

  • Bubble Columns - an overview ScienceDirect Topics

    2.2.5 Bubble column photobiorectors. A bubble column photobioreactor (BCPBR) is basically a cylindrical vessel with a gas distributor at the bottom. The gas is sparged as bubbles into either a liquid phase or a liquid-solid suspension [89]. They consist of different parts cylinders, tubes used for gas inlet, gas outlet and an air pump [90].
