Abstract
A packing material for chromatography or a packing material for a pre-treatment comprises a packing material consisting of a metal or a metal compound reactive with the sulfur-containing compound or a packing material whose surface is coated with the foregoing metal or metal compound; and a sulfur-containing compound bonded to the surface of the foregoing packing material and a kit for preparing a packing material for chromatography or a packing material for a pre-treatment comprises the foregoing packing material; and a sulfur-containing compound. This packing material has a hydrophobic field established by groups such as octadecyl groups, which is never eliminated therefrom even under acidic and alkaline conditions; has thus a high separation and a long service life; can easily be prepared within a short period of time; and therefore, the production cost thereof is quite low.
