| Subject of the standard: | This document specifies a method to determine the total organic carbon (TOC), dissolved organic carbon (DOC), total bound nitrogen (TNb) and dissolved bound nitrogen (DNb) in the form of free ammonia, ammonium, nitrite, nitrate and organic compounds capable of conversion to nitrogen oxides. Cyanide, cyanate and particles of elemental carbon (soot), when present in the sample, can be determined together with the organic carbon. Dissolved nitrogen gas (N2) is not determined. NOTE Generally, the method can be applied for the determination of total carbon (TC) and total inorganic carbon (TIC) – see Annex A. The method is applicable to water samples (e.g. drinking water, raw water, ground water, surface water, sea water, waste water, leachates). This document is applicable to determination of TOC and DOC ?1 mg/l and TNb and DNb ?1 mg/l. The upper working range is restricted by instrument-dependent conditions (e.g. injection volume). Higher concentrations can be determined after appropriate ... |
