US EPA methods: standards and mixes

Transcription

1 US EPA methods: standards and mixes The United States Environmental Protection Agency 500, 600 and 8000 series test methods are approved protocols for measuring chemical pollutants in drinking water (series 500), industrial / urban effluents (series 600), ground water (series 8000) and air, soils and water taken from hazardous waste sites (CLP series). This product range includes mixtures of standards in solution, applicable to specific EPA methods within each of these series.
