  • ANALYSIS SYSTEM AND ANALYSIS METHOD USING SAME
    Publication number: 20250053920
    Abstract: An analysis system includes: an analyzer that performs an analysis using polymer filled in a polymer cartridge, acquires attribute information on the polymer cartridge, and transmits the attribute information to the outside; and a server that acquires the attribute information on the polymer cartridge transmitted from the analyzer, collates the attribute information with attribute information stored in a database, and transmits to the analyzer a determination result obtained by determining whether or not the polymer cartridge in which polymer corresponding to the collated attribute information has been filled already is proper as an object to be set on the analyzer.

  • Liquid chromatograph, liquid chromatograph column and filter for liquid chromatograph column
    Patent number: 9110073
    Abstract: 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.
