  • FILTER WITH SUPPORT CAGE
    Publication number: 20110042289
    Abstract: The invention relates to a filter element for a chromatographic column (1), comprising a support cage (3) whose outer contour defines a cylinder open on one side, and a filter (10) which abuts the inside of the support cage (3). The invention further provides a chromatographic separating column which has a syringe-shaped column element (2) which is open at one end and is provided at the other end with a tapered outlet (11) and into which such a filter element (3, 10) has been inserted.

  • Chromatography material
    Patent number: 5843312
    Abstract: A chromatography material is described for separation of nucleic acid mixtures in which a support is converted with a silanization reagent, in which the silanization reagent has a reactive group converted with silanization reagent, in which the silanization reagent has a reactive group converted with an alkyl- or dialkylamine, or contains a reactive group that can be converted with an alkyl- or dialkylamine, which is then reacted with the alkyl- or dialkylamine.
