Patent ID: 7523642

Claim:
A method for determining fractions of coolants emitted into an atmosphere in processes using coolants, including metal processing industries, which comprises the steps of: feeding samples of the atmosphere polluted with the fractions of coolants in droplet and vapor form to an evaporator; fractionating the fractions of coolants in droplet form contained in the samples according to prespecified sizes, and separately feeding each of the fractions of coolants in droplet form, which have been fractionated according to their sizes, to the evaporator; evaporating, in the evaporator, the fractions of coolants in droplet form contained in the samples; subsequently feeding a vapor resulting from the fractions of coolants in droplet form to an analysis unit together with the fractions of coolants in vapor form contained in the samples; and ascertaining, in the analysis unit, concentrations of the coolants contained in the samples.
