Basic Information
Scope
This document describes the measurement methods for trichloromethane, tribromomethane, dichlorobromomethane, monochlorodibromomethane, dibromomethane, chlorobromomethane, hydrogen cyanide, formaldehyde, acetaldehyde, trichloroacetaldehyde, monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid, dibromoacetic acid, 2,4,6-trichlorophenol, chlorite, chlorate, bromate, nitrosodimethylamine, and trichloromethane in drinking water (capillary column gas chromatography), formaldehyde, acetaldehyde, trichloroacetaldehyde (headspace gas chromatography), monochloroacetic acid (liquid-liquid extraction derivatization gas chromatography), dichloroacetic acid (liquid-liquid extraction derivatization gas chromatography), trichloroacetic acid (liquid-liquid extraction derivatization gas chromatography), 2,4,6-trichlorophenol (derivatization gas chromatography), chlorite (ion chromatography), chlorate (ion chromatography), bromate (ion chromatography-hydroxide system rinsing solution, ion chromatography-carbonate system rinsing solution), and nitrosodimethylamine (solid phase extraction gas chromatography-mass spectrometry). This document is applicable to the determination of disinfection by-products in drinking water and/or source water.
