SOLID PHASE EXTRACTION METHOD USING MICRO DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/040458
Kind Code:
A1
Abstract:
The present invention provides a solid phase extraction method using a micro device having a dam forming portion including a dam, the solid phase extraction method comprising the steps of: (i) injecting a solvent and a filler into the micro device, moving the solvent to a dam forming portion including a dam designed to allow the solvent to flow therethrough and prevent the filler from passing therethrough, and adsorbing a material to be separated to the filler in the dam forming portion; and (ii) extracting, from the filler, the adsorbed material to be separated, wherein the micro device is rotated with respect to the central axis in one of steps (i) and (ii), and the rotation of the micro device is performed at an angular velocity defined by equation 1.
