METHOD 1660 – PYRETHRINS & PYRETHROIDSMethod 1660 is applicable to the determination of pyrethrins and pyrethroids in municipal and industrial wastewater by extraction andhigh-performance liquid chromatography (HPLC) with an ultra-violet detector (UV). Separation and measurement of the pyrethrins and pyrethroidsis performed by reverse-phase Cl8 column HPLC with a multiple-wavelength UV detector.PYRETHRINS & PYRETHROIDSMIXTURE #1EPA METHOD 1660PYRETHRINS & PYRETHROIDSMIXTURE #2EPA METHOD 1660EPA 1600400ug/mL Cyfl uthrin400ug/mL d-(cis-trans)-Phenothrin200ug/mL Fenvalerate400ug/mL TetramethrinMixture in Acetonitrile - (4 components)PP1660-1M 5mLPP1660-1JM 1mL Ampule Allethrin Resmethrin Permethrin400ug/mL in Acetonitrile - (3 components)PP1660-2M 5mLPP1660-2JM 1mL AmpulePYRETHRUM STANDARDEPA METHOD 1660PS-97 100mg PyrethrumMETHOD 1663 – PETROLEUM HYDROCARBONSMethod 1663 is applicable to the determination of petroleum hydrocarbons in municipal and industrial waster water by GC.

Extractable materials that may be determined are non-volatile hydrocarbons, vegetable oils, animal fats, waxes,soaps, greases, and related materials, as well as materials other than aliphatic petroleum hydrocarbons. This method was developed to replacepreviously used gravimetric procedures that employed Freon 113, (a Class I CFC), as the extraction solvent for the determination of oil, greaseand petroleum hydrocarbons by extraction and gravimetry.OIL & GREASE SPIKING MIXTUREEPA METHOD 1664, TPH n-Hexadecane Stearic acid4000ug/mL in Acetone - (2 components)OG1664-1M 5mL AmpuleOG1664-1JM 1mL Ampule 201
