Table of Contents < Method 8020/8020A Method 8030 >  Method 8021/8021A/8021B The SW-846 methods 8021/8021A/8021B are analytical methods which utilize purge & trap device for the sample prep of almost all types of samples and a gas chromatograph equipped with a megabore capillary column to perform the separation of the volatileorganic components found in a sample. To detect the GC eluant, both Hall and photoionization detectors (PID) are used.  Combination Blend Benzene Bromobenzene Bromochloromethane Bromodichloromethane Bromoform n-Butylbenzene sec-Butylbenzene tert-Butylbenzene Carbon tetrachloride Chlorobenzene Chloroform 2-Chlorotoluene 4-Chlorotoluene Combination Blend 1,2-Dibromo-3-chloropropane Dibromochloromethane 1,2-Dibromoethane Dibromomethane 1,2-Dichlorobenzene 1,3-Dichlorobenzene 1,4-Dichlorobenzene 1,1-Dichloroethane 1,2-Dichloroethane 1,1-Dichloroethene cis-1,2-Dichloroethene trans-1,2-Dichloroethene 1,2-Dichloropropane 1,3-Dichloropropane 2,2-Dichloropropane 1,1-Dichloropropene cis-1,3-Dichloropropene trans-1,3-Dichloropropene Ethylbenzene Hexachlorobutadiene Isopropylbenzene p-Isopropyltoluene Methylene chloride Naphthalene n-Propylbenzene Styrene 1,1,1,2-Tetrachloroethane 1,1,2,2-Tetrachloroethane Tetrachloroethene Toluene 1,2,3-Trichlorobenzene 1,2,4-Trichlorobenzene 1,1,1-Trichloroethane 1,1,2-Trichloroethane Trichloroethene 1,2,3-Trichloropropane 1,2,4-Trimethylbenzene 1,3,5-Trimethylbenzene m-Xylene o-Xylene p-Xylene         1.2 mL @ 2000 µg/ml in METH-P&T   Catalog#: 5242-VCX           1.2 ML X 4 PACK   Catalog#: 5242-VCX-4           1.2 mL @ 0 in METH-P&T   Catalog#: 5242-VCX200       METH 502.2 INT STD 2-Bromo-1-chloropropane Fluorobenzene         1.2 mL @ 1000 µg/ml in METH-P&T   Catalog#: 5022-I       Method 8021B (Direct Injection) Benzyl chloride Bromoacetone 2-Chloroethanol Chloromethyl methyl ether 1,3-Dichloro-2-propanol Epichlorhydrin         1.2 mL @ 2000 µg/ml in METH-P&T   Catalog#: 8021B-XB       Method 8021B Analytes Allyl chloride bis(2-Chloroisopropyl)ether 2-Chloro-1,3-butadiene 2-Chloroethyl vinyl ether         1.2 mL @ 2000 µg/ml in METH-P&T   Catalog#: 8021B-XA       Surrogate Standard 1,4-Dichlorobutane           1.2 mL @ 1000 µg/ml in METH-P&T   Catalog#: 8021B-S       V53-524(NO BROMOCHLOROMETHANE) Benzene Bromobenzene Bromodichloromethane Bromoform n-Butylbenzene sec-Butylbenzene tert-Butylbenzene Carbon tetrachloride Chlorobenzene Chloroform 2-Chlorotoluene 4-Chlorotoluene 1,2-Dibromo-3-chloropropane Dibromochloromethane 1,2-Dibromoethane Dibromomethane 1,2-Dichlorobenzene 1,3-Dichlorobenzene 1,4-Dichlorobenzene 1,1-Dichloroethane 1,2-Dichloroethane 1,1-Dichloroethene cis-1,2-Dichloroethene trans-1,2-Dichloroethene 1,2-Dichloropropane 1,3-Dichloropropane 2,2-Dichloropropane 1,1-Dichloropropene cis-1,3-Dichloropropene trans-1,3-Dichloropropene Ethylbenzene Hexachlorobutadiene Isopropylbenzene p-Isopropyltoluene Methylene chloride Naphthalene n-Propylbenzene Styrene 1,1,1,2-Tetrachloroethane 1,1,2,2-Tetrachloroethane Tetrachloroethene Toluene 1,2,3-Trichlorobenzene 1,2,4-Trichlorobenzene 1,1,1-Trichloroethane 1,1,2-Trichloroethane Trichloroethene 1,2,3-Trichloropropane 1,2,4-Trimethylbenzene 1,3,5-Trimethylbenzene m-Xylene o-Xylene p-Xylene         1.2 mL @ 2000 µg/ml in METH-P&T   Catalog#: V53-524           1.2 mL @ 200 µg/ml in METH-P&T   Catalog#: V53-524200
