The work

21、 of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmen

22、tal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the

23、ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibi

24、lity that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

34、inking water, surface water, ground water, waste water and eluates).Taking into account the specific and additionally occurring interferences, these elements can also be determined in digests of water, sludges and sediments (for example, digests of water as described in ISO 15587-1 or ISO 15587-2).T

35、he working range depends on the matrix and the interferences encountered. In drinking water and relatively unpolluted waters, the limit of quantification (xLQ) lies between 0,002 g/l and 1,0 g/l for most elements (see Table 1). The working range typically covers concentrations between several pg/l a

36、nd mg/l depending on the element and pre-defined requirements.The quantification limits of most elements are affected by blank contamination and depend predominantly on the laboratory air-handling facilities available on the purity of reagents and the cleanliness of glassware.The lower limit of quan

37、tification is higher in cases where the determination suffers from interferences (see Clause 5) or memory effects (see ISO 17294-1:2004, 8.2).INTERNATIONAL STANDARD ISO 17294-2:2016(E) ISO 2016 All rights reserved 1BS EN ISO 17294-2:2016ISO 17294-2:2016(E)Table 1 Lower limits of quantification ( xLQ
