Seitdem die Anzahl der PFAS und ihre&nbsp;Verbreitung zugenommen haben, wurden von Regierungsbeh\u00f6rden und Wissenschaftsgemeinden auf der ganzen Welt neuere Methoden zur PFAS-Analyse und Leitf\u00e4den f\u00fcr eine gr\u00f6\u00dfere Auswahl von Verbindungen und Probenmatrices entwickelt. Die folgenden Tabellen, die nach Regionen geordnet sind, bieten einen \u00dcberblick \u00fcber den Umfang der aktuellen Methoden und Richtlinien zur PFAS-Analyse.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">F\u00fcr Labore, die mit PFAS-Analysn beginnen oder neue Verbindungen oder Matrices zu ihrem Testprogramm hinzuf\u00fcgen, k\u00f6nnen die Methoden- und Richtlinienzusammenfassungen in den folgenden Links dabei helfen, Methoden zu vergleichen, einen geeigneten Arbeitsablauf auszuw\u00e4hlen und die richtigen Materialien zu finden.

Diese Standardarbeitsanweisungen (SOPs) und Probenahmeprotokolle sichern die Datenintegrit\u00e4t und erm\u00f6glichen einen pr\u00e4zisen Nachweis im Ultraspurenbereich.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Methoden f\u00fcr den Bereich Wasser werden kontinuierlich weiterentwickelt, um die Extraktionseffizienz zu verbessern und zuverl\u00e4ssige Ergebnisse beim Nachweis von PFAS in Trinkwasser sowie in Nichttrinkwasserproben wie Oberfl\u00e4chenwasser, Grundwasser und Abwasser sicherzustellen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Methoden f\u00fcr komplexere Matrices wie Lebensmittel, Boden, Kl\u00e4rschlamm, Deponiesickerwasser und Gewebe erfordern hingegen h\u00e4ufig andere Extraktions- und Clean-up-Strategien, setzen f\u00fcr die gezielte Analyse jedoch weiterhin auf LC-MS\/MS. In manchen Forschungs- und Screening-Workflows kann zudem die hochaufl\u00f6sende Massenspektrometrie (HRMS) eingesetzt werden, um ein breiteres Spektrum an Verbindungen zu untersuchen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vergleichen Sie anhand der nachstehenden Testmethoden den Matrixumfang, die Analytabdeckung und die analytischen Ans\u00e4tze.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Europ\u00e4ische PFAS-Testmethoden und -Richtlinien (DIN, EU-Verordnungen)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Europ\u00e4ische Rahmenregelungen legen Wert auf harmonisierte Standardmethoden f\u00fcr die Analyse von PFAS in verschiedenen Umweltmedien, um eine einheitliche Vorgehensweise in allen Mitgliedstaaten sicherzustellen \u2013 einschlie\u00dflich der Anforderungen im Rahmen der EU-Trinkwasserrichtlinie.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div
