Abstract:
1. A monolith type separation column including a monolith rod which is cylindrically formed with a porous material and into which a sample and a mobile phase flow, the separation column comprising: a coating material coated on the outer circumference of the monolith rod; a support member into which the monolith rod coated with the coating material is inserted; a rod fixing material filling a gap between the coating material and the support member; a sealing member for preventing said sample from flowing into said rod fixing material, said sealing member having a tapered upper outer surface, a tapered lower outer surface, and an inner surface, and said sealing member contacting an outer peripheral surface of said coating material, an inflow-side end surface of said rod fixing material, an outflow-side end surface of said rod fixing material, and said support member to seal said inflow-side end surface and said outflow-side end surface of said rod fixing material; and a push-on member for pushing and pressing said sealing member toward said outer peripheral surface of said coating material, said inflow-side end surface of said rod fixing material, said outflow-side end surface of said rod fixing material, and said support member, said push-on member having a tapered inner surface that engages said tapered upper outer surface of said sealing member; a diffusion member disposed on an upstream side of the monolith rod for introducing the sample to the monolith rod while allowing diffusion of the sample; and a packing member for pushing and pressing the push-on member toward said sealing member and having an inner circumference surrounding the diffusion member,
