The laboratory performed malysis via <br /> #" modified FPA Method TO-14 using GC/MS in the full scan mode. The method involves concentrating up to <br /> 0S liters of air- The concentrated aliquot is then fash vaporized and swept through a water mamgement <br /> system to remove water vapor. Following dehumidtficatlon, the, sarnple passes direcdy into the GC;/MS for <br /> analysis. See the data sheets for the reporting lid for each compound. <br /> Method modT=tions taken to run these samples include: <br /> Requirement 7044 ATL Madfflica iaer,r <br /> Internal standard retention Not specified.
