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)

active, Most Current
Organization: SNV
Publication Date: 1 November 2011
Status: active
Page Count: 24
ICS Code (Plastics in general): 83.080.01
scope:

This International Standard specifies a general method for determining the average molecular mass and molecular mass distribution of polymers 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 greater-than 1,2.
