22、networking permitted without license from IHS-,-,-iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. E
23、ach member body interested in a subject for which a tec hnical committee has beenestablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closelywith the Internatio
24、nal Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordancewith the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards
25、adopted by the technical committees are circulated to the member bodies for voting. Public ation as an International Standard requires approval byat least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of
26、patent rights. ISO shall not be held responsible for identifying an y or all such patent rights. ISO18857-2 was prepared by Technical Committee ISO/TC147, Water quality, Subcommittee SC 2, Physical,chemical and biochemical methods.

32、This part of ISO 18857 does not purport to address all of the safety problems, if any, associated withits use. It is the responsibility of the user to establish appropriate safetyand health practices and toensure compliance with any national regulatory conditions. IMPORTANT It is absolutely essentia
33、l that testsconducted in accordance with this part of ISO 18857be carried out by suitablyqualified staff.1 Scope This part of ISO18857 specifies a gas chromatographic-mass s pectrometric (GC-MS) determination of selected alkylphenols, their ethoxylates and bisphenolA in non-filtered samples of drink
34、ing, ground, surface, and waste watersfollowing solid-phase extractionand derivatisation. The lower limit of the working range depends on the matrix, on the specific compound to be analysed andon the sensitivityof the mass spectrometric detection unit. The method is applicable in a working range fro
35、m0,005 g/l to 0,2 g/l for 4-(1,1,3,3-tetramethylbutyl)phenol (OP), and its mono- (OP1 EO) and diethoxylate (OP2 EO), from 0,03 g/l to 0,2 g/l for 4-nonylphenol (mixture of isomers)(NP), and its mono- (NP1 EO) anddiethoxylate (NP 2 EO), and from 0,05 g/l to 0,2 g/l for bisphenol A (BPA). Depending on
36、 the matrix, the method is also applicable to waste water in a working range from 0,1 g/l to50g/l for OP, OP 1 EO, OP2 EO and BPA, and from 0,5g/l to 50 g/l for NP, NP 1 EO and NP 2 EO. The working ranges are based on experimental work carried out in ruggedness testing. Water samples containingsuspe

Avoidcontact wit
45、h plastics and other organic materials during sampling, sample storage or extraction. Commercially available adsorbent materials are often of varying quality. Considerable batch-to-batchdifferences in quality and selectivity of this material are possible. The recovery of single substances can varywi

Perform calibration and analysis with material from the same batch. 4.2Gas chromatography-mass spectrometrySubstances with retention times or which produce masses similar to the
47、 analytes to be determined caninterfere with the determination. These interferences may lead to incompletely resolved signals and to additional signals in the chromatographic patternof NP, NP1 EO and NP 2 EO. They may,depending on their magnitude, affectaccuracy and precision of the analytical resul

It is important that the interfering peaks are not included in the calculations. The presence of interfering compounds can, if necessary, be detected by recording full mass spectra (range of mass fragmentsto monitor m / z = 50 to m / z = 350). Matrix interferences can be caused by contaminants that are co-extracted from the sample. The extent of matrix interferences variesconsiderably, depending on the nature of the sample. In drinki
