Automated Gas Chromatograph Evaluation Study

In 2013, the EPA initiated an evaluation of commercially available automated gas chromatographs for potential use in the Photochemical Assessments Monitoring Stations program.  The study included a laboratory evaluation of eight systems.  Based on the results of the laboratory study, a field evaluation of the six best performing systems was conducted.  This page contains links to the final reports for the laboratory and field evaluations.
