Description / Abstract:
This part of ISO 16014 specifies a general method for
determining the average molecular mass and the molecular mass
distribution of polymers using SEC-LS, i.e. size-exclusion
chromatography coupled with lightscattering detection. The average
molecular mass and the molecular mass distribution are calculated
from molecular mass data and mass concentrations determined
continuously with elution time. The molecular mass at each elution
time is determined absolutely by combining a light-scattering
detector with a concentrationsensitive detector. Therefore, SEC-LS
is classified as an absolute method.
For the applicability of the method, see ISO 16014-1:2012,
Clause A.1.
