Table of Contents < Method 624 Method 627-645 >  Method 625 The USEPA method 625 method which utilizes a methylene chloride extraction of municipal or industrial wastewater, concentrated to 1-mL (in methylene chloride) and a gas chromatograph equipped with either a packed or capillary column to perform theseparation of acid and base-neutral extractable fractions. To detect the GC eluant, a mass spectrometer detector is used.  3-3'-DICHLOROBENZIDINE STOCK ST 3,3'-Dichlorobenzidine           1.2 mL @ 2000 µg/ml in METH   Catalog#: CLPS-E       4-COMPONENT GC-MS TUNING STD Benzidine Bis(pentafluorophenyl)phenylphosphine p,p'-DDT Pentachlorophenol         1.2 mL @ 2500 µg/ml in METH   Catalog#: CLPS-T4       5 ML SURRS 2-Fluorobiphenyl 2-Fluorophenol Nitrobenzene-d5 Phenol-d6 p-Terphenyl-d14 2,4,6-Tribromophenol         5.2 mL @ 1000 µg/ml in MC-AC   Catalog#: CLPS-SB5           5.2 mL @ 1000 µg/ml in Methylene   Catalog#: CLPS-SB5-TI           5.2 mL @ 2000 µg/ml in METH   Catalog#: CLPS-SA5           5.2 mL @ 2000 µg/ml in Methanol   Catalog#: CLPS-SA5-TI       ACID SURRS For CLP 2-88 SOW 2-Fluorophenol Phenol-d6 2,4,6-Tribromophenol           1.2 mL @ 2000 µg/ml in METH   Catalog#: CLPS-SA           1.2 mL @ 2000 µg/ml in Methanol   Catalog#: CLPS-SA-TI       ACIDS MATRIX SPIKE 4-Chloro-3-methylphenol 2-Chlorophenol 4-Nitrophenol Pentachlorophenol Phenol           1.2 mL @ 2000 µg/ml in MC   Catalog#: CLPS-MSA           5.2 mL @ 2000 µg/ml in MC   Catalog#: CLPS-MSA5       AROCLOR MIXTURES Aroclor 1242 Aroclor 1254 Aroclor 1016 Aroclor 1221 Arochlor 1232 Aroclor 1248 Aroclor 1260         10 mL @ 200 µg/ml in HEX   Catalog#: PCB-M1           1.2 mL @ 200 µg/ml in HEX   Catalog#: PCB-M2       BASE-NEUTRAL SURR For CLP SOW 2-Fluorobiphenyl Nitrobenzene-d5 p-Terphenyl-d14           1.2 mL @ 1000 µg/ml in MC-AC   Catalog#: CLPS-SB           1.2 mL @ 1000 µg/ml in Methylene   Catalog#: CLPS-SB-TI       BASE-NEUTRALS MATRIX SPIKE Acenaphthene 1,4-Dichlorobenzene 2,4-Dinitrotoluene N-Nitrosodi-n-propylamine Pyrene 1,2,4-Trichlorobenzene         1.2 mL @ 1000 µg/ml in MC   Catalog#: CLPS-MSB           5.2 mL @ 1000 µg/ml in MC   Catalog#: CLPS-MSB5       BIG-BN-2 Acenaphthene Acenaphthylene Anthracene Benz(a)anthracene Benzo(a)pyrene Benzo(b)fluoranthene Benzo(g,h,i)perylene Benzo(k)fluoranthene Benzyl alcohol bis(2-Chloroethoxy)methane bis(2-Chloroisopropyl)ether bis(2-Ethylhexyl)phthalate 4-Bromodiphenyl ether Di-n-butyl phthalate Butylbenzyl phthalate 4-Chloroaniline (p-Chloroaniline) bis(2-Chloroethyl)ether 2-Chloronaphthalene 4-Chlorophenyl-phenyl ether Chrysene Dibenz(a,h)anthracene Dibenzofuran 1,2-Dichlorobenzene 1,3-Dichlorobenzene 1,4-Dichlorobenzene Diethyl phthalate Dimethyl phthalate 2,4-Dinitrotoluene 2,6-Dinitrotoluene Fluoranthene Fluorene Hexachlorobenzene Hexachlorobutadiene Hexachlorocyclopentadiene Hexachloroethane Indeno(1,2,3-c,d)pyrene Isophorone 2-Methylnaphthalene Naphthalene 2-Nitroaniline 3-Nitroaniline 4-Nitroaniline Nitrobenzene N-Nitrosodi-n-propylamine N-Nitrosodiphenylamine Di-n-octyl Phthalate Phenanthrene Pyrene 1,2,4-Trichlorobenzene           1.2 mL @ 2000 µg/ml in MCHLORBEN   Catalog#: BIG-BN-2           1.2ml x 4   Catalog#: BIG-BN-2-4           5 mL @ 2000 µg/ml in MCHLORBEN   Catalog#: BIG-BN-2-5       BIG-BN-2, 625-E, 625-F,625-PH BIG-BN-2, 625-E, 625-F,625-PH           1.2 mL @ 0 in MC   Catalog#: 625-K-3       Chlordane Chlordane           1.2 mL @ 1000 µg/ml in HEX   Catalog#: S-780       CHLORDANE STOCK STD Chlordane           1.2 mL @ 200 µg/ml in HEX   Catalog#: CDANE-X           1.2 mL @ 2000 µg/ml in HEX   Catalog#: CDANE-XH       CHLORINATED-NITRATED HYDROCARB 2-Chloronaphthalene 1,2-Dichlorobenzene 1,3-Dichlorobenzene 1,4-Dichlorobenzene 2,4-Dinitrotoluene 2,6-Dinitrotoluene Hexachlorobenzene Hexachlorobutadiene Hexachlorocyclopentadiene Hexachloroethane Isophorone Nitrobenzene 1,2,4-Trichlorobenzene           1.2 mL @ 2000 µg/ml in MC   Catalog#: CLPS-D       CLP MIX F Benzoic acid 2-Methylphenol 4-Methylphenol 2,4,5-Trichlorophenol         25 mL @ 2000 µg/ml in MC   Catalog#: CLPS-F       CLP MIX G Benzyl alcohol 4-Chloroaniline (p-Chloroaniline) Dibenzofuran 2-Methylnaphthalene 2-Nitroaniline 3-Nitroaniline 4-Nitroaniline           1.2 mL @ 2000 µg/ml in MC   Catalog#: CLPS-G       CLPS-C,CLPS-D,625-E,625-F,625-PH CLPS-C,CLPS-D,625-E,625-F,625-PH           1.2 mL @ 0 in MC   Catalog#: 625-K-1       GC-MS TEST MIX Bis(pentafluorophenyl)phenylphosphine Pentachlorophenol         1.2 mL @ 250 µg/ml in MC   Catalog#: 625-T2       GC-MS TUNING STD Bis(pentafluorophenyl)phenylphosphine           1.2 mL @ 2500 µg/ml in METH   Catalog#: CLPS-T       HALOETHERS & PHTHALATES bis(2-Chloroethoxy)methane bis(2-Chloroisopropyl)ether bis(2-Ethylhexyl)phthalate 4-Bromodiphenyl ether Di-n-butyl phthalate Butylbenzyl phthalate bis(2-Chloroethyl)ether 4-Chlorophenyl-phenyl ether Diethyl phthalate Dimethyl phthalate N-Nitrosodi-n-propylamine N-Nitrosodiphenylamine Di-n-octyl Phthalate           1.2 mL @ 2000 µg/ml in MC   Catalog#: CLPS-C           1.2 ML X 4 PACK   Catalog#: CLPS-C-4           5.2 mL @ 2000 µg/ml in MC   Catalog#: CLPS-C5       IND.
