1、Designation:D616021Standard Test Method forDetermination of Polychlorinated Biphenyls(PCBs)in WasteMaterials by Gas Chromatography1This standard is issued under the fixed designation D6160;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revis
2、ion,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method2covers a two-tiered analytical ap-proach to PCB screening and quantitation of liquid and
3、solidwastes,such as oils,sludges,aqueous solutions,and otherwaste matrices.1.2 Tier I is designed to screen samples rapidly for thepresence of PCBs.1.3 Tier II is used to determine the concentration of PCBs,typically in the range of from 2 mg kg to 50 mg kg.PCBconcentrations greater than 50 mg/kg ar
4、e determined throughanalysis of sample dilutions.1.4 This is a pattern recognition approach,which does nottake into account individual congeners that might occur,suchas in reaction by-products.This test method describes the useof Aroclors31016,1221,1232,1242,1248,1254,1260,1262,and 1268,as reference
5、 standards,but others could also beincluded.Aroclors 1016 and 1242 have similar capillary gaschromatography(GC)patterns.Interferences or weathering areespecially problematic withAroclors 1016,1232,and 1242 andmay make distinction between the three difficult.1.5 This test method provides sample clean
6、 up and instru-mental conditions necessary for the determination of Aroclors.Gas chromatography(GC)using capillary column separationtechnique and electron capture detector(ECD)are described.Other detectors,such as atomic emission detector(AED)andmass spectrometry(MS),may be used if sufficient perfor
7、mance(for example,sensitivity)is demonstrated.Further details aboutthe use of GC and ECD are provided in Practices E355,E697,and E1510.1.6 Quantitative results are reported on the dry weights ofwaste samples.1.7 Quantification limits will vary depending on the type ofwaste stream being analyzed.1.8
8、The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.9 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate
