β¦ Synopsis
Gas chromatography Megabore columns Rapid purge and trap Purgeable pollutants
As specified by the United States Environmental Protection Agency (USEPA) [5], P&T analysis involves an 11.0 rnin purge of a 5 mL sample at 40 mL/min followed by, a 4.0 min thermal listed in Table 2. The PID and ELCD were connected in series, with a 23 cm x 0.53 mm i.d. section of uncoated deactivated fused silica.

Experiments were carried out to check the validity of the method used to calculate gas fluxes in the windtunnel technique. This method assumes that the airflow is completely mixed downwind of the emission plot. This hypothesis was tested using a homogeneously distributed CO source installed on the g
