_ AI'nY'TICAL PROGEDC M FOR <br /> THE DETECTION AND QUANTIFICATION CF TOTKL- PETRO <br /> FUEL AYDROCAP3W6 AND FUEL CONSITUESTS The following analytical procedures and analysis shall be used <br /> for the detection and quantification of patraleum hydrocarbons <br /> &rid - fuel c=stituemts. Mum* techniques are to be followed wbatn _ <br /> analysis is' required for evaluation of either a suspactad or <br /> confirmed tank leek asL presented in the quidalines. Vies• <br /> analytical techniques cover - the full zvmge of petroleum fuel <br /> hocarbo s from gasoli"_ CC4-C Z) to jet feel tC - -C ) � to <br /> ,jdr ( -C 2) in sithar a Iiquic� or solid matrix. t�%*2&on of <br /> compl-ex ydAKarbon mixtures. ars beat achieved . .using Gas <br /> Chra=tograph with a Flags Ionization Detector (GC/FI.D) . <br /> I. 2dT1PETROUM, EM HYDROME&M AMMIR <br /> (Low to medium boiling point hydrocarbons) <br /> - This includes the full rdnga of solin .

Pra2arati4n - <br /> 1, Witter <br /> Use EPA method 5020-x- 8eadspace or EPA method 5030,' <br /> Purge and Trsp, (EPA Manual SW-846, April 1984) . <br /> Methanol extractic m should be used in those casae <br /> where the sample is representative of an aged <br /> Vial, or it is desired that the heavier ends of <br /> gasoline tart _to be extracted. <br /> 2. Soil <br /> Use EFA method 5020, Headepact or EPA method 5030, <br /> purge and Trap, (EFA sanual SW-8461, April 1984-) .; <br /> Methanol extaction should be used in those cauls <br /> where - the sample.. is representative of an aged <br /> _ fuel, or it is daairsd that tzie heavier grids of <br /> gasoline ars to be extracted. <br /> N.
