METHOD 9060A TOTAL ORGANIC CARBON - US EPA

TOTAL ORGANIC CARBON 1.0 SCOPE AND APPLICATION 1.1 This method is used to determine the concentration of organic carbon in ground water, surface and saline waters, and domestic and industrial wastes. Some restrictions are noted in Secs. 2.0 and 3.0. 1.2 This method is most applicable to measurement of organic carbon above 1 mg/L. 2.0 SUMMARY OF

Water Sampling Vials - VWR

To meet EPA standards and prevent contamination, vials are prepared in a solvent-free facility. Test for toxicity with clear, white, or amber vials for ultraviolet sensitive samples. Since water sampling procedures demand immediate testing for accurate results, open-top, closed-top, attached, or screw on cap options permit quick access to contents. Septa closure options also come in various materials for content compatibility.
