  • Publication number: 20200166486
    Abstract: A liquid delivery device includes a liquid delivery pump that sucks a mobile phase, which is liquid, from a mobile phase container containing the mobile phase through a suction pipe whose end is immersed in the mobile phase in the mobile phase container, and feeds the mobile phase, and at least one dissolved substance removal filter that is provided at a position upstream of the liquid delivery pump on a path through which the mobile phase flows and is filled with a filler having the property of adsorbing a dissolved substance in the mobile phase.

  • Publication number: 20180361353
    Abstract: The present invention provides a chromatographic separating agent which exhibits excellent performances in separation of organic compounds, such as reducing sugars without formation of Schiff bases and anomer separation in analysis of saccharides. The chromatographic separating agent includes a porous substrate surface-modified with silane functional groups represented by the formula: wherein R1 represents an alkylene group or oxyalkylene group having a carbon number of 1 to 10. R2 and R3 independently represent an alkylene group or alkyleneoxyalkylene group having a carbon number of 1 to 6.

  • Patent number: 8101073
    Abstract: The present invention relates to a separating agent for solid-phase extraction which comprises core particles of a base material; a hydrophilic polymer layer formed on the surface of the particles; and a hydrophobic polymer layer formed on the surface of the hydrophilic polymer layer. The separating agent can be used in a cartridge or a column for solid-phase extraction and the latter can in turn be used in a variety of methods such as a method for concentrating a subject to be separated; a method for removing impurities; a method for solid-phase extraction of an environmental, medicinal and/or biological samples; and a method for pre-treating a protein component-containing sample.
