Title:
COLUMN TUBE FOR CHROMATOGRAPHY, AND COLUMN FOR CHROMATOGRAPHY EMPLOYING SAME
Document Type and Number:
WIPO Patent Application WO/2018/212165
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a column tube for chromatography with which it is possible to prevent a peak shape abnormality known as a fit in a resulting chromatogram. This problem is resolved by means of a column tube for chromatography through the inside of which a fluid flows, wherein the column tube has on an inner peripheral surface thereof a plurality of polishing streaks extending in the direction in which the fluid flows.
