Abstract The objectives of the study were to install, test and demonstrate two automated gas chromatographic (GC) systems to state and regional EPA groups. The Dynatherm/Hewlett Packard GC system was designed for the measurement of the 41 toxic compounds listed in EPA's Compendium of Methods for Method TO-14. The second system was a Perkin Elmer GC configured for the analysis of the 55 ozone precursor compounds identified in the EPA Technical Assistance Document No. EPA/600-8-91/215. Both GC systems performed well during the field evaluations with data capture of 98 percent. A method quantitation limit (MQL) of 0.5 ppbv was obtained for most of the target compounds. In examining daily control check runs, the variation of corrected GC retention times for each instrument and detector ranged from 0.023 to 0.044 minutes.
