Gel permeation chromatography (GPC) - Part 1: Tetrahydrofuran (THF) as eluent (ISO 13885-1:2020)

This document specifies the determination of the molar-mass distribution and the average molar mass values Mn (number average) and Mw (weight average) of polymers that are soluble in tetrahydrofuran (THF) by gel permeation chromatography (GPC).
NOTE    Also known as size exclusion chromatography (SEC).
Even though the chromatograms obtained show good repeatability, it is possible that this method cannot be used with certain polymer types because of specific interactions (e.g. adsorption) within the sample/eluent/column system.
The conditions specified in this document are not applicable to the GPC analysis of polymer samples with Mw values greater than 106 g/mol and/or of polymers with elution limits outside the calibration range (see 7.6 and Annex C).
This document includes no correction method (e.g. for the elimination of peak broadening. If absolute molar-mass values are required, an absolute method (e.g. membrane osmometry for Mn or light scattering for Mw) can be used.

Gelpermeationschromatographie (GPC) - Teil 1: Tetrahydrofuran (THF) als Elutionsmittel (ISO 13885-1:2020)

Dieses Dokument legt die Ermittlung der Molmassenverteilung und der Molmassenmittelwerte Mn (Zahlenmittel) und Mw (Gewichtsmittel) von in Tetrahydrofuran (THF) löslichen Polymeren durch Gelpermeationschromatographie (GPC) fest.
ANMERKUNG Im Englischen auch als „size exclusion chromatography“ (SEC), übersetzt „Größenausschluss-chromatographie“, bekannt.
Auf Grund spezifischer Wechselwirkungen (z. B. Adsorption) in dem System aus Probe/Elutionsmittel/Trennmaterial ist es möglich, dass dieses Verfahren trotz guter Wiederholbarkeit der resultierenden Chromatogramme auf einzelne Polymere nicht angewandt werden kann.
Die in diesem Dokument festgelegten Bedingungen sind nicht anwendbar bei GPC-Analysen von Polymerproben mit Mw-Werten größer 106 g/mol und/oder von Polymeren, deren Elutionsgrenzen außerhalb des Kalibrierbereiches liegen (siehe 7.6 und Anhang C).
Dieses Dokument umfasst keine Korrekturverfahren (z. B. Elimination der Peakverbreiterung). Wenn absolute Molmassenwerte benötigt werden, kann auf ein Absolutverfahren (z. B. Membranosmometrie für Mn oder Lichtstreuung für Mw) zurückgegriffen werden.
WARNUNG - Dieses Dokument kann den Umgang mit gefährlichen Substanzen und Ausrüstungsteilen und die Ausführung gefährlicher Arbeitsgänge einschließen. Es erhebt nicht den Anspruch, auf alle gegebenenfalls vorhandenen und mit seiner Anwendung verbundenen Sicherheitsprobleme hinzuweisen. Es liegt in der Verantwortung des Anwenders, geeignete Vorkehrungen für den Arbeits‑ und Gesundheitsschutz zu treffen und die Übereinstimmung mit jeglichen nationalen Bestimmungen sicherzustellen.

Chromatographie par perméation de gel (GPC) - Partie 1: Utilisation de tétrahydrofurane (THF) comme éluant (ISO 13885-1:2020)

Le présent document spécifie la détermination de la distribution de masses molaires et des valeurs de masse molaire moyenne Mn (moyenne en nombre) et Mw (moyenne en masse) de polymères solubles dans le tétrahydrofurane (THF) par chromatographie de perméation de gel (GPC, de l’anglais «gel permeation chromatography »).
NOTE            Également appelée chromatographie d’exclusion stérique (SEC, de l’anglais «size exclusion chromatography »).
Même si les chromatogrammes obtenus présentent une bonne répétabilité, il est possible que cette méthode ne puisse pas être utilisée avec certains types de polymères du fait d’interactions spécifiques (par exemple, adsorption) dans le système échantillon/éluant/colonne.
Les conditions spécifiées dans le présent document ne sont pas applicables à l’analyse GPC d’échantillons de polymères présentant des valeurs Mw supérieures à 106 g/mol et/ou de polymères dont les limites d’élution se situent en dehors de la gamme d’étalonnage (voir 7.6 et Annexe C).
Le présent document n’inclut pas de méthode de correction (par exemple, pour l’élimination d’un élargissement des pics). Si des valeurs absolues de masse molaire sont exigées, une méthode absolue (par exemple, osmométrie à membrane pour Mn ou diffusion de lumière pour Mw) peut être utilisée.
