Title:
DEGASSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/016946
Kind Code:
A1
Abstract:
A vacuum type degassing device that uses a gas-liquid separation membrane, wherein both end parts of a degassing tube (14) disposed within a vacuum chamber are connected to flow path connection parts (12, 13) provided in a chamber cover part (11), and the tube is accommodated within the vacuum chamber while being coiled in a loop shape. At three locations in the loop-shaped part (14c) of the degassing tube (14), multiple degassing tubes (14) are bound and joined by fluorine resin tape that is softer than gas permeable material constituting the tubes. Thus, even when fluctuations arise in a mobile phase flow within the degassing tube (14) or the flow becomes intermittent, undulations in the degassing tube (14) do not occur easily, and friction between the tubes is prevented even if undulations occur. As a result, the degassing tube (14) is prevented from becoming thinner because of abrasion, and occurrences of cracks, which cause liquid leakage, can be avoided.
