标准范围

ISO 17294-2:2003规定了铝、锑、砷、钡、铍、铋、硼、镉、铯、钙、铈、铬、钴、铜、镝、铒、铕、钆、镓、锗、金、铪、钬、铟、铱、镧、铅、锂、镥、镁、锰、钼、钕、镍、，钯、磷、铂、钾、镨、铷、铼、铑、钌、钐、钪、硒、银、钠、锶、铽、碲、钍、铊、铥、锡、钨、铀、钒、钇、镱、锌和水中的锆（例如饮用水、地表水、地下水、废水和洗脱液）。考虑到特定的和额外发生的干扰，这些元素也可以在水、淤泥和沉积物的消化液中测定。工作范围取决于矩阵和遇到的干扰。在饮用水和相对未受污染的水中，大多数元素的应用限制在0.1微克/升到1.0微克/升之间。大多数元素的检测限受空白污染的影响，主要取决于可用的实验室空气处理设施。在测定可能受到干扰或记忆影响的情况下，应用的下限更高。

ISO 17294-2:2003 specifies a method for the determination of the elements aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, caesium, calcium, cerium, chromium, cobalt, copper, dysprosium, erbium, europium, gadolinium, gallium, germanium, gold, hafnium, holmium, indium, iridium, lanthanum, lead, lithium, lutetium, magnesium, manganese, molybdenum, neodymium, nickel, palladium, phosphorus, platinum, potassium, praseodymium, rubidium, rhenium, rhodium, ruthenium, samarium, scandium, selenium, silver, sodium, strontium, terbium, tellurium, thorium, thallium, thulium, tin, tungsten, uranium, vanadium, yttrium, ytterbium, zinc, and zirconium in water (for example drinking water, surface water, groundwater, wastewater and eluates).Taking into account the specific and additionally occurring interferences, these elements can also be determined in digests of water, sludges and sediments.The working range depends on the matrix and the interferences encountered. In drinking water and relatively unpolluted waters, the limit of application is between 0,1 micrograms per litre and 1,0 micrograms per litre for most elements.The detection limits of most elements are affected by blank contamination and depend predominantly on the laboratory air-handling facilities available.The lower limit of application is higher in cases where the determination is likely to suffer from interferences or in case of memory effects.
