The invention relates to a stationary phase medium for adsorption chromatography, which is in form of porous particles suitable for being packed into a chromatographic column. The porous particles are made of cross-linked polymeric material and formed with interconnected macropores to constitute a porous network, through which a mobile phase fluid may flow in a convective manner. The porous particles are substantially free of diffusive pores and, thus, the mass transfer through the porous network is governed by convection alone. The porous particles are fabricated to have irregular granular configurations with rough outer surfaces, so that the convective flow between the porous particles will not be impeded during chromatography process.

Stationary phase medium for adsorption chromatography and manufacturing method thereof

The invention relates to production of a porous microstructure using the high internal phase emulsion (HIPE) templating technology. The invented method involves subjecting an emulsion prepared by emulsification of two immiscible phases to forced sedimentation, such as subjecting the emulsion to centrifugation, so as to increase the volume ratio of the dispersed phase to the continuous phase to obtain a high internal phase emulsion (HIPE), following by curing the continuous phase, whereby the porous microstructure thus produced has an increased porosity.

Method for producing porous microstructure

An apparatus for isolating bubbles from a liquid comprises at least a main body; an inlet tube and an outlet tube disposed at a side of the main body which includes an accommodation chamber and a column disposed atop, the inlet tube is formed with an aperture within the accommodation chamber, and the outlet tube is disposed at a position below the inlet tube; and a coupling tube disposed within the accommodation chamber, and includes a first end connected to the inlet tube and a second end corresponding to and separating from the outlet tube by a gap. During use, a liquid dispersed with bubbles is introduced through the inlet tube. The bubbles pass through the aperture along with a small portion of the liquid and ascend toward a top of the accommodation chamber and are then collected by the column.
