Table of Contents < Method 607 Method 608.1 >  Method 608 The USEPA method 608 is an analytical method which utilizes a methylene chloride extraction of municipal or industrial wastewater, concentrated to 10-mL (in hexane) and a gas chromatograph equipped with a packed column to perform the separation oforganochlorine pesticides and PCB's. To detect the GC eluant, an ECD (electron capture) detector is used.  608 STD MIX Compound µg/mL Aldrin 100 alpha-BHC 100 beta-BHC 100 p,p'-DDD 600 p,p'-DDE 200 delta-BHC 100 Dieldrin 200 p,p'-DDT 600 Compound µg/mL Endosulfan I 200 Endosulfan II 200 Endosulfan sulfate 600 Endrin 200 Endrin aldehyde 600 gamma-BHC 100 Heptachlor 100 Heptachlor epoxide 100         1.2 mL @ 100 µg/ml in METH   Catalog#: 608-A           1.2 mL @ 200 µg/ml in METH   Catalog#: 608-A           1.2 mL @ 600 µg/ml in METH   Catalog#: 608-A       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       IND.
