Abstract

Solid sorption agent for TLC comprises a coating of a binder-free polyamide film consisting of intimately entangled, finely-fibrous polyamide crystals, upon a solid substance (e.g. a glass plate or Al-foil). The polyamide film is applied by immersing the substrate into a soln. of polyamide in e.g. phenol or propylene glycol.
