  • Thin porous layers for thin-layer chromatography
    Patent number: 6395178
    Abstract: Novel separation materials for thin layer chromatography are disclosed; these consist of a support and a separation medium layer and are obtainable by the following process steps: a) cleaning of the support; b) application of a liquid film comprising a polysilicic ester to a support; c) introduction of the support with the liquid film into an atmosphere which effects hydrolysis and further polymerization of the polysilicic ester; d) hydrolysis and further polymerization of the polysilicic ester at constant temperature; e) washing of the silica layer; f) drying of the silica layer. The silica gel surface of the separation material of the invention can be modified by means of separation effectors.

  • Column clamping device for chromatography
    Patent number: 4451365
    Abstract: The device is a clamping and sealing apparatus for use with separation columns, i.e., chromatographic columns. Sealing elements having sealing means extending therefrom are provided at each end of a column with at least one being movable in an axial direction and controlled by pressure generating means. The sealing members are shaped corresponding to the ends of the column to fit flush against the column and to provide a seal when actuated by the pressure generating means.
