A field-deployable prototype fast gas chromatograph (FGC) and two commercially-available portable gas chromatographs (PGC) were evaluated by measuring organic vapors in ambient air at a field monitoring site in metropolitan San Juan, Puerto Rico. The data were compared with simultaneous grab samples which were collected in six-liter Summa-polished canisters and analyzed by method TO-14. Because of fluctuating retention times, the FGC produced no useable data. High humidity levels may have adversely affected its performance. Both commercially-available PGCs performed successfully, and data from twenty analyses were compared with the reference method.
