7. A method of analysis, comprising the steps of:
generating a gas flow through a separator from an inlet side to an outlet side of said separator, said gas comprising a process gas which has processed incoherent plastics;
detecting a concentration of total organic carbon, or total organic carbon without acetaldehyde, or total organic carbon without methane, or acetaldehyde, or methane, in the gas in said inlet side and/or in said outlet side; and
determining at least one operating condition of said separator on the basis of the concentration detected in said outlet side and/or determining at least one operating condition of said gas flow on the basis of the concentration detected in said inlet side.
 
18. Analysis apparatus, comprising:
an activated carbon filtration device with an inlet side and an outlet side;
a flow generator for generating a gas flow through said filtration device from said inlet side to said outlet side;
a gas chromatography analysis instrument configured to measure concentration of total organic carbon in the gas in said inlet side and in said outlet side, said analysis instrument being connected with at least one sampling point of gas samples from said inlet side and from said outlet side;
means for determining at least one operating condition on the basis of said measured concentration; and
means for comparing a concentration of total organic carbon in said inlet side and a concentration of total organic carbon in said outlet side.
