US EPA Method 8270D
US EPA Method 8270, Semivolatiles in water offers a large list of analytes that can be monitored in many clean and waste matrices. It can be paired with US EPA Method 3535A for solid phase extraction sample preparation.
Horizon Technology has developed an effective one-pass method, passing the acidified sample through an SPE disk and then through a carbon cartridge, if needed. This avoids the second step, where the sample is basified and extracted again, often causing emulsions.
US EPA Method 3535A
US EPA 8081
US EPA 8081 is similar to drinking water method 508 and the wastewater method 608 for organochlorine pesticides providing additional sensitivity with a halogen-specific detector.
US EPA 8082
US EPA Method 8082 is specific for polychlorinated biphenyls (PCBs), including Aroclor multicomponent mixtures and congeners using a halogen-specific detector on a GC.
US EPA 8015
US EPA Method 8015 is a method for non-halogenated organics using GC-FID. The method can be used for measurement of a variety of individual compounds or the petroleum hydrocarbons include gasoline range organics (GRO) and diesel range organics (DRO).
US EPA 8141
US EPA Method 8141 is a method providing procedures for the gas chromatographic (GC) determination of organophosphorus (OP) compounds. Gas Chromatography equipped with a flame photometric detector (FPD) or a nitrogen-phosphorus detector (NPD).
US EPA 8330B
US EPA Method 8330B is used for nitroaromatics, nitramines, and nitrate esters by HPLC. The method specifically mentions that solid phase extraction provides advantages, particularly when the analytes are present at low concentrations.
