Abstract

See full text

A method for analyzing a droplet fraction of an oil mist sample of a gas turbine is provided. A collecting device collects the oil mist sample, wherein the collecting device is arranged within a breather pipe which is coupled to the gas turbine such that oil mist is flowing through the breather pipe. The droplet fraction is separated from a gaseous fraction of the oil mist sample by a filter device, wherein the filter device is soaked with the droplet fraction, the droplet fraction is extracted from the filter device by using a tetrachloroethylene solvent. A composition of the droplet fraction is analyzed by a spectrometer.
