CD-ROM 8015B - 1 Revision 2,December 1996,METHOD 8015B,NONHALOGENATED ORGANICS USING GC/FID,1.0 SCOPE AND APPLICATION,1.1 Method 8015 is used to determine the concentration of various nonhalogenated volatile,organic compounds and semivolatile organic compounds by gas chromatography. The following,compounds can be determined quantitatively by this method:,Appropriate Technique,Compound Name Purge-and- Direct Solvent,CAS No.a Trap Injection Extraction,Acetone 67-64-1 pp b,d I,Acetonitrile 75-05-8 pp b,d I,Acrolein 107-02-8 pp b,d I,Acrylonitrile 107-13-1 pp b,d I,Allyl alcohol 107-18-6 ht b,d I,1-Butanol (n-Butyl alcohol) 71-36-3 ht b,d I,t-Butyl alcohol 75-65-0 pp b,d I,2-Chloroacrylonitrile (I.S.) 920-37-6 NA d NA,Crotonaldehyde 123-73-9 pp b,d I,Diethyl ether 60-29-7 b b I,1,4-Dioxane 123-91-1 pp b,d I,Ethanol 64-17-5 I b,d I,Ethyl acetate 141-78-6 I b,d I,Ethylene glycol 107-21-1 I b I,Ethylene oxide 75-21-8 I b,d I,Hexafluoro-2-propanol (I.S.) 920-66-1 NA d NA,Hexafluoro-2-methyl-,2-propanol (I.S.) 515-14-6 NA d NA,Isobutyl alcohol 78-83-1 pp b,d I,Isopropyl alcohol 67-63-0 pp b,d I,Methanol 67-56-1 I b,d I,Methyl ethyl ketone (MEK) 78-93-3 pp b,d I,Methyl isobutyl ketone (MIBK) 108-10-1 pp b,d I,N-Nitroso-di-n-butylamine 924-16-3 pp b,d b,Paraldehyde 123-63-7 pp b,d I,2-Pentanone 107-87-9 pp b,d I,2-Picoline 109-06-8 pp b,d I,1-Propanol 71-23-8 pp b,d I,Propionitrile 107-12-0 ht d I,CD-ROM 8015B - 2 Revision 2,December 1996,Appropriate Technique,Compound Name Purge-and- Direct Solvent,CAS No.a Trap Injection Extraction,Pyridine 110-86-1 I b,d b,o-Toluidine 95-53-4 I b,d b,a Chemical Abstract Services Registry Number.,b Adequate response using this technique,d Amenable to concentration by azeotropic distillation (Method 5031),ht Method analyte only when purged at 80EC,I Inappropriate technique for this analyte,pp Poor purging efficiency, resulting in high EQLs,NA Not available,I.S. Internal standard appropriate for Method 5031,1.2 This method may also be applicable to the analysis of petroleum hydrocarbons, including,gasoline range organics (GROs) and diesel range organics (DROs). GROs correspond to the range,of alkanes from C to C and covering a boiling point range of approximately 60EC - 170EC 6 10,(Reference 6). DROs correspond to the range of alkanes from C to C and covering a boiling point 10 28,range of approximately 170EC - 430EC (Reference 6). The identification of specific fuel types may,be complicated by environmental processes such as evaporation, biodegradation, or when more,than one fuel type is present. Methods from other sources may be more appropriate for GROs and,DROs, since these hydrocarbons are not regulated under RCRA. Consult State and local regulatory,authorities for specific requirements.,1.3 This method is restricted for use by, or under the supervision of, analysts experienced,in the use of gas chromatographs and skilled in the interpretation of gas chromatograms. In addition,if this method is used for the analysis of petroleum hydrocarbons, it is limited to analysts experienced,in the interpretation of hydrocarbon data. Each analyst must demonstrate the ability to generate,acceptable results with this method.,1.4 The method can also be used as a screening tool (for both volatile and semivolatile,organics) to obtain semiquantitative data for the prevention of sample overload during quantitative,analysis on a GC/MS system. This may be accomplished using an automated (Method 5021),headspace method or by direct injection if a solvent extraction method has been utilized for sample,preparation. Single point calibration would be acceptable in this situation. Performance data are,not provided for screening.,2.0 SUMMARY OF METHOD,2.1 Method 8015 provides gas chromatographic conditions for the detection of certain,nonhalogenated volatile and semivolatile organic compounds.,2.1.1 Samples may be introduced into the GC:,@ following solvent extraction (Methods 3510, 3520, 3540, 3541, 3545, 3550, or,3560),CD-ROM 8015B - 3 Revision 2,December 1996,@ by direct injection (aqueous samples) including the concentration of analytes by,azeotropic distillation (Method 5031),@ by purge-and-trap (Methods 5030 or 5035), or,@ by vacuum distillation (Method 5032),2.1.2 Ground or surface water samples must generally be analyzed in conjunction with,Methods 5030, 5031, 5032, 3510, 3520, or other appropriate preparatory methods to obtain,the necessary quantitation limits. Method 3535 (solid-phase extraction) may also be applicable,to the target analytes, but has not yet been validated by EPA in conjunction with Method 8015.,2.1.3 Diesel range organics (DROs) may be prepared by……
