Abstract

The invention relates to a process and an apparatus for the selective on-line identification and distinguishing of pollutants and contents in bottles/containers in filling systems in the beverage or drinks industry using the absorption, reflection and scattering of electromagnetic waves from the UV to the microwave range, characterized in that characteristic value pairs/ranges of wavelength and amplitude are used for identification and distinguishing.
