25、ights reserved vIntroduction In recent years, ground water contamination as well as surface water contamination by pesticides has become a matter of public concern. Identification and quantification of pesticides at trace level concentrations often require both high sensitive chromatographic equipme
26、nt and effective enrichment steps. In the analysis of aqueous samples, sample preparation techniques including solid-phase extraction (SPE) are frequently the most time-consuming steps and in many cases can be effectively replaced by solid-phase microextraction (SPME). When using this International
27、Standard, it may be necessary in some cases to determine whether and to what extent particular problems could require the specification of additional marginal conditions. BS EN ISO 27108:2013ISO 27108:2010ivBS ISO 27108:2010ISO 27108:2010(E) iv ISO 2010 All rights reservedForeword ISO (the Internati
28、onal 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. Each member body interested in a subject for which a technical committee has been
29、established 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 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standar
30、dization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for v
31、oting. Publication as an International Standard requires approval by at 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 patent rights. ISO shall not be held responsible for identifying any or all s
32、uch patent rights. ISO 27108 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical, chemical and biochemical methods.

34、metry (GC-MS) WARNING Persons using this International Standard should be familiar with normal laboratory practice. This International Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safet
35、y and health practices and to ensure compliance with any national regulatory conditions. IMPORTANT It is absolutely essential that tests conducted according to this International Standard be carried out by suitably trained staff. 1 Scope This International Standard specifies a method for the determi
36、nation of the dissolved amount of selected plant treatment agents and biocide products in drinking water, ground water and surface water by solid-phase microextraction (SPME) followed by gas chromatography-mass spectrometry (GC-MS). The limit of determination depends on the matrix, on the specific c
37、ompound to be analysed and on the sensitivity of the mass spectrometer. For most plant treatment agents and biocides to which this International Standard applies, it is at least 0,05 g/l. Validation data related to a concentration range between 0,05 g/l and 0,3 g/l have been demonstrated in an inter
38、laboratory trial. This method may be applicable to other compounds not explicitly covered by this International Standard or to other types of water. However, it is necessary to verify the applicability of this method for these special cases. NOTE Determinations by this International Standard are per
39、formed on small sample amounts (e.g. sample volumes between 8 ml and 16 ml). 2 Normative references The following referenced documents are indispensable for the application of this document.

43、suitable adsorbent polymer. During extraction, the fibre is immersed in the liquid sample. After completion of the extraction procedure, the fibre is drawn back into the needle, removed from the sample vial, and introduced directly into the GC injector. The analytes are transferred to the GC column

The analytes are separated, identified and quantified by means of capillary gas chromatography with mass spectrometric detection (GC-MS) using electron impact (EI) ionisation mode.
