Water quality - Determination of selected phthalates using gas chromatography/mass spectrometry (ISO 18856:2004)

ISO 18856:2004 specifies a method for the determination of phthalates in water after solid phase extraction and gas chromatography/mass spectrometry.
This method is applicable to the determination of phthalates in ground water, surface water, wastewater and drinking water in mass concentrations ranging from above 0,02 microgram per litre up to 0,150 microgram per litre, depending on the individual substance and the value of the blank.
The applicability of this method to other phthalates not specified is not excluded, but it is necessary to determine its applicability in each case.

Wasserbeschaffenheit - Bestimmung ausgewählter Phthalate mittels Gaschromatographie/Massenspektrometrie (ISO 18856:2004)

Diese Internationale Norm legt ein Verfahren für die Bestimmung von Phthalaten in Wasser nach Festphasenextraktion mittels Gaschromatographie/Massenspektrometrie fest.
Das Verfahren ist anwendbar auf die Bestimmung von Phthalaten (siehe Tabelle 1) in Grundwasser, Oberflächenwasser, Abwasser und Trinkwasser in Massenkonzentrationen von 0,02 µg/l bis 0,150 µg/l, abhängig von der individuellen Substanz und der Höhe des Blindwerts.
Das Verfahren darf auch auf andere in der Tabelle 1 nicht spezifizierte Phthalate angewendet werden, die Eignung muss jedoch in jedem Fall geprüft werden (siehe Anhang A, Liste von Phthalaten).
Allgemeine Anmerkungen zur Wiederfindung und zum Gebrauch eines internen Standards sind in Anhang B enthalten.

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. 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-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 standardization.
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 voting. 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 such patent rights.
ISO 18856 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical,
chemical and biochemical methods.

Introduction
The user should be aware that particular problems could require the specification of additional marginal
conditions.
INTERNATIONAL STANDARD ISO 18856:2004(E)

Water quality — Determination of selected phthalates using gas
chromatography/mass spectrometry
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 safety 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 determination of phthalates in water after solid phase
extraction and gas chromatography/mass spectrometry.
This method is applicable to the determination of phthalates (see Table 1) in ground water, surface water,
wastewater and drinking water in mass concentrations ranging from above 0,02 µg/l up to 0,150 µg/l,
depending on the individual substance and the value of the blank.
The applicability of this method to other phthalates not specified in Table 1 is not excluded, but it is necessary
to determine its applicability in each case (see Annex A for the list of phthalates).
General remarks concerning the recovery and use of internal standards is given in Annex B.

references, only the edition cited applies. For undated references, the latest edition of the reference document
(including any amendments) applies.

3 Principle
Extraction of the compounds from the water by solid-phase extraction. Then separation is accomplished using
capillary columns by gas chromatography and followed by identification and quantification of the phthalates by
mass spectrometry. The principle of this method is outlined in Figure 1.
