Plastics - Determination of average molecular mass and molecular mass distribution of polymers using size-exclusion chromatography - Part 5: Method using light-scattering detection (ISO 16014-5:2012)

The standard specifies a general method for determining the average molecular mass and molecular mass distribution of polymers from using SEC-LS, i.e. size-exclusion chromatography (SEC) coupled with light scattering detection (LS). The average molecular mass and the molecular mass distribution are calculated from data of molecular mass and mass concentration determined continuously at eacht elution time. The molecular mass at each elution time is determined absolutely by combining a light scattering detector with a concentration-sensitive detector. Therefore this method is classified as an absolute method (see Clause A.1 in Annes A).

Kunststoffe - Bestimmung der durchschnittlichen Molmasse und der Molmassenverteilung von Polymeren mittels Gelpermeationschromatographie - Teil 5: Lichtstreudetektionsverfahren (ISO 16014-5:2012)

Dieser Teil von ISO 16014 legt ein allgemeines Verfahren zum Bestimmen der durchschnittlichen Molmasse und der Molmassenverteilung von Polymeren durch GPC-LS, d. h. Gelpermeationschromatographie (GPC), gekoppelt mit Messung durch Lichtstreuung (LS), fest. Die durchschnittliche Molmasse und die Molmassenverteilung werden aus den Daten für die Molmasse und die Massenkonzentrationen berechnet, die kontinuierlich mit der Elutionszeit bestimmt werden. Die Molmasse bei jeder Elutionszeit wird als Absolutwert bestimmt, indem ein Detektor für die Lichtstreuung mit einem Konzentrationsdetektor kombiniert wird. Die GPC-LS wird deshalb als ein absolutes Verfahren klassifiziert.
Zur Anwendbarkeit des Verfahrens siehe ISO 16014-1:2012, Abschnitt A.1.

Polimerni materiali - Določevanje povprečne molekularne mase in porazdelitev molekularne mase polimerov z uporabo izključitvene kromatografije (SEC) - 5. del: Metoda s sipanjem svetlobe (ISO 16014-5:2012)

Ta del standarda ISO 16014 določa splošno metodo za ugotavljanje povprečne molekulske mase in porazdelitev molekulske mase polimerov z uporabo izključitvene kromatografije skupaj s sipanjem svetlobe (SEC-LS). Povprečna molekulska masa in porazdelitev molekulske mase se izračunata na podlagi podatkov o molekulski masi in koncentraciji mase, ki se kontinuirano določa z elucijskim časom. Molekulska masa se za posamezni elucijski čas določi absolutno s kombinacijo sipanja svetlobe in na koncentracijo občutljivega detektorja. Zato se izključitvena kromatografija skupaj s sipanjem svetlobe šteje za absolutno metodo. Za uporabo metode glejte točko A.1 standarda ISO 16014-1:2012.
