| Subject of the standard: | This International Standard specifies a method for the determination of total organic carbon (TOC), dissolved organic carbon (DOC), and for the determination of dissolved and particular bound nitrogen (TNb) in the form of free ammonia, ammonium, nitrite, nitrate and organic compounds capable of conversion to nitrogen oxides under the oxidative conditions described. The procedure is carried out instrumentally. NOTE 1 Generally the method can be applied for the determination of total carbon (TC) and total inorganic carbon (TIC) (see Annex A in the Outline). The method is applicable for water (e.g. drinking water, raw water, ground water, surface water, sea water or waste water) containing suspended material of ? 100 µm of particle size (convention). Reduce particles of > 100 µm of size to pieces of particle size of ? 100 µm before injection. |
