Instrument for polycyclic aromatic hydrocarbon analysis of airborne particles by capillary gas chromatography with laserinduced fluorescence detection

Sammanfattning

The proposed method is based on the idea that by combining thermal desorption injection, capillary chromatographic separation and fluorescence detection, the pretreatment (extraction and clean-up) normally preceding gas chromatographic analysis of particulate polycyclic aromatic hydrocarbons can be omitted without sacrificing too much in terms of delectability and resolution. The advantages of the method are that only a small volume of air is necessary, as most of the sample can be injected in the same analysis, and that the time and cost per analysis are reduced. This allows measurements with good resolution in time and space as well as the use of small, lightweights sampling equipment, e.g., for use in exposure studies in factories.
