摘要:
A column for chromatography includes a flow path for allowing a mobile phase, the flow path including mutually-opposing sidewalls and a bottom wall joined to the sidewalls and arranged at bottom ends of the sidewalls; and a plurality of pillars provided to extend along the sidewalls from the bottom wall and regularly arranged at a specified interval. The column is configured to separate individual components from a mixture sample containing multiple kinds of components by using the pillars as a stationary phase. Each of the pillars includes a curved outer surface and the sidewalls partially include a curved surface conforming to the outer surface of each of the pillars. The shortest distance between each of the sidewalls and a pillar positioned closest to said each of the sidewalls is equal to the shortest distance between the pillars in a flow direction of the mobile phase.
摘要:
A micro-channel device provided in a solution analysis system using pressure liquid feed comprises a plurality of straight-line channels and curved channels connecting the ends of the neighboring straight-line channels. The width w of each curved channel is smaller than the width t of each straight-line channel. The radius of curvature r of each curved channel is set so that the value of a expressed by formula (1) is equal to or smaller than the value of a at a local maximum point of the theoretical step height H expressed by formula (2) and based on the shape of the curved channel. a=w/r (1) H = u c w 2 64 γ D m × a 2 ( a + 2 ) a + 1 ( 2 ) Where, w is a width of the curved channel, uc is a channel passing speed of a solution in the curved channel, γ is a molecular diffusion inhibition factor by basic members present in the curved channel, and Dm is a molecular diffusion coefficient of the solution.
