METHOD FOR MANUFACTURING THIN LAYER CHROMATOGRAPHY PLATES

摘要

A method for manufacturing a thin layer chromatography ("TLC") plate (100) is disclosed. The method includes forming a catalyst layer (104) disposed on a substrate that includes a first portion and at least a second portion, each of the first and at least a second portions exhibiting a selected non-linear configuration. The method also includes forming a layer of elongated nanostructures (e.g. carbon nanotubes), and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase is functionalized with hydroxyl groups by exposure to acidified water vapor or immersion in a concentrated acid liquid bath (e.g. HCI and methanol). At least a portion of the elongated nanostructures are removed after being coated.
