Liquid permeation rate inspection column, liquid permeation rate detector

摘要

An object of the present invention is to realize high-accuracy liquid permeation rate inspection of a sample. A liquid permeation rate measuring column 100 is disposed at a lower end of a cylindrical portion 110 in which a sample F is filled and at the lower end of the cylindrical portion 110 and holds a lower surface F1 of a sample F and passes a liquid E. And the sample pressing portion 130 disposed in the cylindrical portion 110 and having the contact surface 130A that contacts the upper surface F2 of the sample F. [Selected figure] Figure 2
