Method for determining the concentration of a volatile substance， emission monitoring device and system for the production of workpieces

A method for determining the concentration of at least one volatile substance which is emitted by at least one workpiece (12， 18)， an emission monitoring device (34) and a system (10) for producing the at least one workpiece (12， 18) are provided ) described. The method is carried out in the system (10) for producing the at least one workpiece (12， 18). At least one measured concentration variable， which characterizes the concentration of at least one volatile substance， is measured in the system (10). The at least one measured concentration variable is correlated with at least one concentration value from at least one reference measurement. The concentration of the at least one volatile substance is determined with the aid of the correlation. The correlation between the at least one measured concentration variable and the at least one concentration value is specified.
