Method and device for determining the fractions of lubricants emitted into the atmosphere in coolant processes

A method for determining fractions of coolants emitted into the atmosphere in processes using coolants, in particular in the metal processing industry. Here, samples of the atmosphere polluted with fractions of coolants in droplet and vapor form are fed to an evaporator. In the evaporator, the fractions of coolants in droplet form contained in the samples are evaporated and subsequently the vapor resulting from the fractions of coolants in droplet form is fed to an analysis unit, in particular a flame ionization detector, together with the fractions of coolants in vapor form contained in the samples. In the analysis unit the concentrations of the coolants contained in the samples are ascertained.
