High-performance liquid chromatographic determination of benzil in air as an indicator of emissions derived from polyester powder coatings

A method to estimate occupational exposure to emissions from the curing of polyester powder paints was developed. The method is based on the monitoring only of a certain marker compound in workroom air in order to make the determinations easier. Benzil, reproducibly emitted from all the powders test...

Summary:A method to estimate occupational exposure to emissions from the curing of polyester powder paints was developed. The method is based on the monitoring only of a certain marker compound in workroom air in order to make the determinations easier. Benzil, reproducibly emitted from all the powders tested, was chosen as the indicator for curing (220 degrees C)-derived emissions. A method for the air sampling and high-performance liquid chromatographic benzil is described. Aspects of the use of marker compounds are discussed.
