摘要： In a liquid chromatograph, the disulfide adsorption of iron atoms in a filter for a column is avoided and thus peak tailing in a chromatogram is prevented to thereby prevent a lowering in the sample recovery rate. A liquid chromatograph column comprising a hollow tubular column body, a bead-shaped packing material which is packed in the hollow part of the column body, a filter provided with a mesh which has a mesh size smaller than the particle diameter of the packing material, and a cap which presses the filter against the packing material to thereby enclose the packing material within the column body, characterized in that the main component of the filter is nickel or hastelloy.

摘要： To provide a column packing, a separation column, an analysis device, and an analysis method to reduce the analysis time without deteriorating the separation of multi-component amino acids. Disclosed are a column packing comprising a core portion made of a styrene-di-vinylbenzene copolymer having a cross-linkage degree of 50% or more and a shell portion made of a styrene-di-vinylbenzene copolymer having a cross-linkage degree of 20% or less; a separation column using the column packing; and a high-speed liquid chromatography analysis device and a analysis method using the separation column.
