Abstract

The invention relates to a method for separating gases of a gas mixture in the form of a gas stream, wherein the gas stream is irradiated with electromagnetically emitted radiation (12) in the microwave or terahertz range, scattered radiation (13) is detected, the scattered radiation arising due to scattering of the emitted radiation at at least one object (11) in the gas stream, a difference in frequency between the scattered radiation and the emitted radiation is detected, a presence, a number and/or a proportion of moving objects in the gas stream is/are determined from the difference in frequency and the separation of the gases of the gas mixture is carried out while taking into account the determined presence, the determined number and/or the determined proportion of moving objects in the gas stream.
