Thin porous layers for thin-layer chromatography |
摘要 |
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.
