(Main)Plastics - Determination of the molecular mass and molecular mass distribution of polymer species by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) (ISO 10927:2018)
Plastics - Determination of the molecular mass and molecular mass distribution of polymer species by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) (ISO 10927:2018)
This document specifies a general method for determining the average molecular mass and molecular mass distribution of polymers (see Reference [1]) from 2 000 g ⋅ mol−1 to 20 000 g ⋅ mol−1 by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).
The average molecular masses and molecular mass distributions are calculated from a calibration curve constructed using synthetic-polymer and/or biopolymer standards. This method is therefore classified as a relative method.
The method is not applicable to polyolefins or to polymers with a polydispersity >1,2.
Kunststoffe - Bestimmung der Molmasse und Molmassenverteilung von polymeren Species durch matrixunterstütze Laser-Desorptions/Ionisations-Flugzeit-Massenspektrometrie (MALDI-TOF-MS) (ISO 10927:2018)
Dieses Dokument legt ein allgemeines Verfahren zum Bestimmen der mittleren Molmasse und der
Molmassenverteilung von Polymeren (siehe Literaturhinweis [1]) in einem Molmassenbereich von
2 000 g ⋅ mol−1 bis 20 000 g ⋅ mol−1 durch die matrixunterstützte Laser-Desorptions/Ionisations-Flugzeit-
Massenspektrometrie (MALDI-TOF-MS) fest.
Die mittleren Molmassen und Molmassenverteilungen werden über eine Kalibrierkurve berechnet, die mit
Hilfe von synthetischen und/oder Biopolymerstandards erstellt wird. Daher handelt es sich um eine relative
Methode.
Das Verfahren ist nicht für Polyolefine oder Polymere mit einer Polydispersität > 1,2 anwendbar.
Plastiques - Détermination de la masse moléculaire et de la distribution des masses moléculaires des polymères par spectrométrie de masse, à temps de vol, après désorption/ionisation laser assistée par matrice (SM-MALDI-TOF) (ISO 10927:2018)
Le présent document spécifie une méthode générale permettant de déterminer la masse moléculaire moyenne et la distribution des masses moléculaires moyennes de polymères (voir Référence [1]) comprises entre 2 000 g ⋅ mol−1 et 20 000 g ⋅ mol−1 par spectrométrie de masse, à temps de vol, après désorption/ionisation laser assistée par matrice (SM-MALDI-TOF).
Les masses moléculaires et les distributions des masses moléculaires moyennes sont calculées à partir d'une courbe d'étalonnage établie à l'aide d'étalons de polymères synthétiques et/ou de biopolymères. Par conséquent, la présente méthode est classée comme méthode relative.
La présente méthode n'est pas applicable aux polyoléfines et aux polymères ayant une polydispersité > 1,2.
Polimerni materiali - Ugotavljanje molekulske mase in porazdelitve molekulske mase polimerov z masno spektrometrijo po laserski desorpciji/ionizaciji v nosilcu (matriksu) (MALDI-TOF-MS) (ISO 10927:2018)
Ta dokument določa splošno metodo za ugotavljanje povprečne molekulske mase in porazdelitve molekulske mase polimerov (glej sklic [1]) od 2000 g ⋅ mol−1 do 20.000 g ⋅ mol−1 z masno spektrometrijo po laserski desorpciji/ionizaciji v nosilcu (matriksu) (MALDI-TOF-MS).
Povprečne molekulske mase in porazdelitve molekulskih mas se izračunajo na podlagi kalibracijske krivulje, izdelane z uporabo standardov za sintetični polimer in/ali biopolimer. Ta metoda je zato klasificirana kot relativna metoda.
Metoda se ne uporablja za poliolefine oziroma polimere s polidisperzijo > 1,2.
