Water quality - Determination of selected plant treatment agents and biocide products - Method using solid-phase microextraction (SPME) followed by gas chromatography-mass spectrometry (GC-MS) (ISO 27108:2010)

ISO 27108:2010 specifies a method for the determination 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 compound to be analysed and on the sensitivity of the mass spectrometer. For most plant treatment agents and biocides to which ISO 27108:2010 applies, it is at least 0,05 µg/l. Validation data related to a concentration range between 0,05 µg/l and 0,3 µg/l have been demonstrated in an interlaboratory trial.
This method may be applicable to other compounds not explicitly covered by ISO 27108:2010 or to other types of water. However, it is necessary to verify the applicability of this method for these special cases.

Wasserbeschaffenheit - Bestimmung ausgewählter Pflanzenschutzmittel und Biozidprodukte - Verfahren mittels Festphasenmikroextraktion (SPME) gefolgt von der Gaschromatographie und Massenspektrometrie (GC-MS) (ISO 27108:2010)

Diese Internationale Norm legt ein Verfahren für die Bestimmung ausgewählter Pflanzenschutzmittel und Biozidprodukte, gelöst in Trink , Grund  und Oberflächenwasser mittels Festphasenmikroextraktion (SPME) und einem gaschromatographischen Verfahren mit massenspektrometrischer Detektion (GC-MS) fest. Die Bestimmungsgrenze des Verfahrens ist abhängig von der Probenmatrix, der jeweils zu untersuchenden Verbindung und der Empfindlichkeit des Massenspektrometers. Für die meisten Pflanzenschutzmittel und Biozidprodukte, auf die sich diese Internationale Norm bezieht, liegt sie mindestens bei 0,05 µg/l. In einem Ringversuch wurden Daten zur Methodenvalidierung in einem Konzentrationsbereich von 0,05 µg/l bis 0,3 µg/l erhoben.
Die Anwendbarkeit des Verfahrens auf weitere, in dieser Internationalen Norm nicht ausdrücklich genannten Verbindungen oder andere Wässer ist nicht ausgeschlossen. Sie muss jedoch im Einzelfall geprüft werden.
ANMERKUNG   Die Bestimmungen nach dieser Internationalen Norm werden mit kleinen Probenvolumina (z. B. zwischen 8 ml und 16 ml) durchgeführt.

Qualité de l'eau - Détermination d'agents de traitement et de produits d'usine sélectionnés - Méthode utilisant une micro-extraction en phase solide (MEPS) suivie d'une chromatographie en phase gazeuse-spectrométrie de masse (CG-SM) (ISO 27108:2010)

L'ISO 27108:2010 spécifie une méthode pour la détermination de la quantité d'agents de traitement et de produits d'usine sélectionnés dissous dans l'eau potable, les eaux souterraines et les eaux de surface par micro-extraction en phase solide (MEPS) suivie d'une chromatographie en phase gazeuse-spectrométrie de masse (CG-SM). La limite de la détermination dépend de la matrice, du composé spécifique à analyser et de la sensibilité du spectromètre de masse. Pour la plupart des agents de traitement et de produits d'usine auxquels l'ISO 27108:2010 s'applique, elle est d'au moins 0,05 µg/l. Les données de validation relatives à une gamme de concentrations comprises entre 0,05 µg/l et 0,3 µg/l ont été démontrées lors d'un essai interlaboratoires.
Cette méthode peut être applicable à d'autres composés qui ne sont pas explicitement traités dans l'ISO 27108:2010 ou à d'autres types d'eau. Toutefois, il est nécessaire de vérifier l'applicabilité de cette méthode à ces cas particuliers.

Kakovost vode - Določevanje izbranih sredstev za zaščito rastlin in biocidov - Metoda s plinsko kromatografijo/masno spektrometrijo (GC/MS) po mikroekstrakciji na trdni fazi (SPME) (ISO 27108:2010)

Ta mednarodni standard določa metodo za določanje raztopljene količine izbranih sredstev za zaščito rastlin in biocidov v pitni vodi, podtalnici in površinski vodi s plinsko kromatografijo/masno spektrometrijo (GC/MS) po mikroekstrakciji na trdni fazi (SPME). Meja določevanja je odvisna od matrice, specifične spojine za analizo in občutljivosti masnega spektometra. Pri večini sredstev za zaščito rastlin in biocidov, za katere velja ta mednarodni standard, znaša ta meja vsaj 0,05 μg/l. Podatki o validaciji, ki se nanašajo na razpon koncentracije med 0,05 μg/l in 0,3 μg/l, so bili prikazani z mednarodnim medlaboratorijskim poskusom. Ta metoda lahko velja za druge spojine, ki niso izrecno zajete v tem mednarodnem standardu, ali za druge vrste vode. Vendar je treba za te posebne primere uporabnost te metode preveriti. OPOMBA: Določbe iz tega mednarodnega standarda izhajajo iz majhnih vzorčnih količin (tj. vzorčni volumen med 8 in 16 ml).

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 27108:2010(E)
Introduction
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 equipment 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 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.

INTERNATIONAL STANDARD ISO 27108:2010(E)

Water quality — Determination of selected plant treatment
agents and biocide products — Method using solid-phase
microextraction (SPME) followed by gas chromatography-mass
spectrometry (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 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 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 compound 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 µg/l. Validation data related to a concentration range between 0,05 µg/l and 0,3 µg/l have
been demonstrated in an interlaboratory trial.
This method may be applicable to other compounds not explicitly covered
