CD-ROM 8240B - 1 Revision 2,September 1994,METHOD 8240B,VOLATILE ORGANIC COMPOUNDS BY GAS CHROMATOGRAPHY/MASS SPECTROMETRY (GC/MS),1.0 SCOPE AND APPLICATION,1.1 Method 8240 is used to determine volatile organic compounds in a,variety of solid waste matrices. This method is applicable to nearly all types,of samples, regardless of water content, including ground water, aqueous sludges,caustic liquors, acid liquors, waste solvents, oily wastes, mousses, tars,fibrous wastes, polymeric emulsions, filter cakes, spent carbons, spent,catalysts, soils, and sediments. The following compounds can be determined by,this method:,______________________________________________________________________________,Appropriate Technique,Direct,Analyte CAS No.b Purge-and-Trap Injection,Acetone 67-64-1 pp a,Acetonitrile 75-05-8 pp a,Acrolein (Propenal) 107-02-8 pp a,Acrylonitrile 107-13-1 pp a,Allyl alcohol 107-18-6 pp a,Allyl chloride 107-05-1 a a,Benzene 71-43-2 a a,Benzyl chloride 100-44-7 pp a,Bromoacetone 598-31-2 pp a,Bromochloromethane (I.S.) 74-97-5 a a,Bromodichloromethane 75-27-4 a a,4-Bromofluorobenzene (surr.) 460-00-4 a a,Bromoform 75-25-2 a a,Bromomethane 74-83-9 a a,2-Butanone (MEK) 78-93-3 pp a,Carbon disulfide 75-15-0 pp a,Carbon tetrachloride 56-23-5 a a,Chloral hydrate 302-17-0 pp a,Chlorobenzene 108-90-7 a a,Chlorobenzene-d5 (I.S.) 3114-55-4 a a,Chlorodibromomethane 124-48-1 a a,Chloroethane 75-00-3 a a,2-Chloroethanol 107-07-3 pp a,bis-(2-Chloroethyl) sulfide 505-60-2 pp a,2-Chloroethyl vinyl ether 110-75-8 a a,Chloroform 67-66-3 a a,Chloromethane 74-87-3 a a,Chloroprene 126-99-8 a pc,3-Chloropropionitrile 542-76-7 ND pc,1,2-Dibromo-3-chloropropane 96-12-8 pp a,1,2-Dibromoethane 106-93-4 a a,CD-ROM 8240B - 2 Revision 2,September 1994,______________________________________________________________________________,Appropriate Technique,Direct,Analyte CAS No.b Purge-and-Trap Injection,Dibromomethane 74-95-3 a a,1,4-Dichloro-2-butene 764-41-0 pp a,Dichlorodifluoromethane 75-71-8 a a,1,1-Dichloroethane 75-34-3 a a,1,2-Dichloroethane 107-06-2 a a,1,2-Dichloroethane-d4(surr.) 107-06-2 a a,1,1-Dichloroethene 75-35-4 a a,trans-1,2-Dichloroethene 156-60-5 a a,1,2-Dichloropropane 78-87-5 a a,1,3-Dichloro-2-propanol 96-23-1 pp a,cis-1,3-Dichloropropene 10061-01-5 a a,trans-1,3-Dichloropropene 10061-02-6 a a,1,2,3,4-Diepoxybutane 1464-53-5 a a,1,4-Difluorobenzene (I.S.) 540-36-3 a a,1,4-Dioxane 123-91-1 pp a,Epichlorohydrin 106-89-8 i a,Ethanol 64-17-5 i a,Ethylbenzene 100-41-4 a a,Ethylene oxide 75-21-8 pp a,Ethyl methacrylate 97-63-2 a a,2-Hexanone 591-78-6 pp a,2-Hydroxypropionitrile 78-97-7 ND pc,Iodomethane 74-88-4 a a,Isobutyl alcohol 78-83-1 pp a,Malononitrile 109-77-3 pp a,Methacrylonitrile 126-98-7 pp a,Methylene chloride 75-09-2 a a,Methyl iodide 74-88-4 a a,Methyl methacrylate 80-62-6 a a,4-Methyl-2-pentanone 108-10-1 pp a,Pentachloroethane 76-01-7 i pc,2-Picoline 109-06-8 pp a,Propargyl alcohol 107-19-7 pp a,-Propiolactone 57-57-8 pp a,Propionitrile 107-12-0 pp a,n-Propylamine 107-10-8 a a,Pyridine 110-86-1 i a,Styrene 100-42-5 a a,1,1,1,2-Tetrachloroethane 630-20-6 a a,1,1,2,2-Tetrachloroethane 79-34-5 a a,Tetrachloroethene 127-18-4 a a,Toluene 108-88-3 a a,Toluene-d8 (surr.) 2037-26-5 a a,1,1,1-Trichloroethane 71-55-6 a a,1,1,2-Trichloroethane 79-00-5 a a,Trichloroethene 79-01-6 a a,Trichlorofluoromethane 75-69-4 a a,CD-ROM 8240B - 3 Revision 2,September 1994,______________________________________________________________________________,Appropriate Technique,Direct,Analyte CAS No.b Purge-and-Trap Injection,1,2,3-Trichloropropane 96-18-4 a a,Vinyl acetate 108-05-4 a a,Vinyl chloride 75-01-4 a a,Xylene (Total) 1330-20-7 a a,a Adequate response by this technique.,b Chemical Abstract Services Registry Number.,pp Poor purging efficiency resulting in high EQLs.,i Inappropriate technique for this analyte.,pc Poor chromatographic behavior.,surr Surrogate,I.S. Internal Standard,ND Not determined,1.2 Method 8240 can be used to quantitate most volatile organic,compounds that have boiling points below 200oC and that are insoluble or slightly,soluble in water. Volatile water-soluble compounds can be included in this,analytical technique. However, for the more soluble compounds, quantitation,limits are approximately ten times higher because of poor purging efficiency.,The method is also limited to compounds that elute as sharp peaks from a GC,column packed with graphitized carbon lightly coated with a carbowax. Such,compounds include low molecular weight halogenated hydrocarbons, aromatics,ketones, nitriles, acetates, acrylates, ethers, and sulfides. See Table 1 for,a list of compounds, rete……
