Determination of carbonyl compounds by HPLC/UV analysis in the CASTNet Air Toxics Monitoring Program (CATMP)
- Environmental Science and Engineering, Inc., Gainesville, FL (United States)
The determination of carbonyl compounds in ambient air is one of the analytical requirements of the Environmental Protection Agency`s (EPA`s) Clean Air Status and Trends Network (CASTNet) Air Toxics Monitoring Program (CATMP). The CATMP was established in 1993 by EPA to reactivate and operate the Urban Air Toxics Monitoring Program (UATMP). The purpose of the program is to establish baseline toxics concentrations, develop air emission inventories, and to identify air toxic sources using chemical mass balance modeling techniques. 1993 results for the CATMP analysis of carbonyl compounds by method TO-11 are presented. Samples were collected using Waters` dinitrophenyl hydrazine (DNPN) impregnated cartridges and analyzed using high performance liquid chromatography (HPLC) with ultraviolet (UV) detection. A regulatory program approach to quality control was taken to insure that all aspects of shipping, sampling and analysis contained sufficient controls in order to produce data of acceptable and consistent precision and accuracy. Database presentations will include the overall quality assurance approach, quality control measurements, and sample results from eight sites. An examination of background interferences detected in the various control samples also is discussed.
