Abstract
The device is based on the use of amorphous thin layers having a thickness of the order of 1000 Angstrom units and a cellular structure on the same scale as the distances between atoms, the structure being homogeneous and isotropic inside the layer. The structure is made of substances which are physically and chemically inert towards the substances to be separated. The cellular structure is due to the incorporation in the layer of elementary particles acting as network dilators or network modifiers.
