Title:

LIQUID FEEDING DEVICE AND FLUID CHROMATOGRAPH

Document Type and Number:

WIPO Patent Application WO/2018/198234

Kind Code:

A1

Abstract:

This liquid feeding device is provided with: a pump head having a pump chamber provided therein; a plunger having a tip part that is slidably inserted into the pump chamber; and at least one plunger pump having a driving mechanism which reciprocates the plunger in the axial direction thereof. Also, the at least one plunger pump is a pressurization pump which pressurizes a mobile phase and then ejects the mobile phase from the pump chamber, wherein the mobile phase is composed of a compressible fluid suctioned into the pump chamber. At least the pump head of the pressurization pump is provided with a cooling part which is connected to an outlet flow path from the pump chamber and cools the mobile phase by absorbing into the pump head, the heat of the mobile phase ejected from the pump chamber.
