Pulp, paper and paperboard - Determination of anthraquinone in extracts from pulp, paper and paperboard
This document specifies an analytical test method for the determination of anthraquinone (see Table 1) in water and 95 % ethanol extracts of pulp, paper and board materials and articles intended to come into contact with foodstuffs using a gas chromatograph coupled to a mass spectrometer (GC-MS). Moreover, acetone extracts of modified polyphenylene oxide (MPPO) that, according to EN 14338, can be used as a simulant to assess the possible transfer/migration of substances from paper and board into dry, non-fatty foodstuffs can be analysed with the method presented here.
This method can be applied to determine anthraquinone in concentrations ranging from 2 μg/l to 40 μg/l in the water and solvent extracts, corresponding to 0,05 mg/kg to 1 mg/kg pulp, paper and board or, respectively, 0,1 μg/dm2 to 2 μg/dm2 in the case of migration tests with MPPO. The measurement range can be lowered by enriching anthraquinone from the water and solvent extracts.
Faserstoff, Papier und Karton - Bestimmung von Anthrachinon in Faserstoff-, Papier- und Kartonextrakten
Dieses Dokument legt ein Analyseverfahren zur Bestimmung von Anthrachinon (siehe Tabelle 1) in Wasser und 95%igen Ethanolextrakten von Faserstoff , Papier und Kartonmaterialien und gegenständen, die dazu bestimmt sind, mit Lebensmitteln in Berührung zu kommen, unter Verwendung eines Gaschromatographen, der mit einem Massenspektrometer gekoppelt ist (GC MS), fest. Darüber hinaus können Aceton Extrakte von modifizierten Polyphenyloxiden (MPPO, en: modified polyphenylene oxide), die nach EN 14338 als Simulanz verwendet werden können, um den möglichen Übergang/die mögliche Migration von Substanzen aus Papier und Karton in trockene, fettfreie Lebensmittel zu beurteilen, mit dem dargestellten Verfahren analysiert werden.
Dieses Verfahren kann angewendet werden, um Anthrachinon in Konzentrationen von 2 µg/l bis 40 µg/l im Wasser beziehungsweise den Lösemittelextrakten, entsprechend 0,05 mg/kg bis 1 mg/kg Faserstoff, Papier und Karton, beziehungsweise 0,1 μg/dm2 bis 2 μg/dm2 im Fall von Migrationsversuchen mit MPPO, zu bestimmen. Der Messbereich kann durch Anreichern von Anthrachinon aus dem Wasser und den Lösemittelextrakten gesenkt werden.

Pâte, papier et carton - Détermination d'anthraquinone dans des extraits de pâte, papier et carton
Le présent document spécifie une méthode d’essai analytique pour la détermination de l’anthraquinone (voir Tableau 1) dans des extraits à l’eau et l’éthanol à 95 % de matériaux et articles destinés à entrer en contact avec les denrées alimentaires sous forme de pâte, papier et carton en utilisant un chromatographe en phase gazeuse couplé à un spectromètre de masse (CG-SM). De plus, des extraits à l’acétone d’oxyde de polyphénylène modifié (MPPO) qui, conformément à l’EN 14338, peuvent être utilisés comme solvant simulant pour évaluer le transfert/la migration possible de substances issues du papier et du carton dans des denrées alimentaires sèches, non grasses, peuvent être analysés par la méthode présentée ici.
Cette méthode peut être appliquée pour déterminer l’anthraquinone dans des concentrations se situant dans la plage de 2 μg/l à 40 μg/l dans les extraits aqueux et de solvant, correspondant à 0,05 mg/kg à 1 mg/kg de pâte, de papier et de carton ou, respectivement, 0,1 μg/dm2 à 2 μg/dm2 dans le cas d’essais de migration avec du MPPO. La plage de mesurage peut être abaissée en enrichissant l’anthraquinone à partir des extraits aqueux et de solvant.

4 Principle
4.1 General
Anthraquinone is extracted from pulp, paper and board with water and/or 95 % ethanol according to
EN 645, EN 647 and/or EN 15519, and with acetone from MPPO which was brought into contact with the
materials as a simulant for dry, non-fatty foodstuffs according to EN 14338. GC-MS is used to determine
the anthraquinone content in the prepared extracts.
4.2 Interferences
Matrix related interferences can occur. In these cases, the quantification of anthraquinone may be
performed by using one of the qualifier ions (12.1.2) or by standard addition.
