Water quality. Determination of selected organic nitrogen and phosphorus compounds. Gas chromatographic methods LONG_TITLE 4 Peripheral AMS measurements1 Scope This International Standard specifies two methods for the determination of certain organic nitrogen and phosphorus compounds in waters by gas chromatography (see Table 1). The methods may be extended to include additional substances, provided the methods are validated for each individual case. Clause 3 describes the liquid liquid extraction method, which is applicable to samples of drinking waters, ground waters, surface waters and waste
