Beschreibung
Zusammenfassung:	One object of the present invention is to prevent non-specific metal coordination adsorption of solutes in a sample, while achieving high pressure resistance through the use of a metal column hardware column, and to prevent non-specific adsorption of basic solutes and non-specific hydrophobic adsorption of highly hydrophobic solutes. As a means for achieving the foregoing, proposed is column hardware 1 for liquid chromatography, in which a first membrane 41 containing SiO2 as a main component is provided on a metallic liquid-contact portion by mobile phase 3 of the column hardware 1 for liquid chromatography, and a second membrane 42 in which silanol groups on the SiO2 surface are alkylsilylated is provided on a surface 411 of the first membrane 41.
