Beschreibung
Zusammenfassung:A supporting substrate for the deposition, automated recognition and spectroscopic identification of particulate impurities in liquid or gaseous media, comprising a filter membrane of polymer materials of a defined pore width, wherein the surface of the filter membrane is coated with metal which in the selected wavelength range for spectroscopic identification has no spectral features and at the selected excitation wavelength absorbs no or only little of the laser energy which is radiated in, and has a very smooth structure.
