标准范围
This International Standard specifies a general method for determining the average molecular mass andmolecular mass distribution of polymers (see Reference [1]) from 2 000 g?mol?1 to 20 000 g?mol?1 by matrixassistedlaser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).The average molecular masses and molecular mass distributions are calculated from a calibration curveconstructed using synthetic-polymer and/or biopolymer standards. This method is therefore classified as arelative method.The method is not applicable to polyolefins or to polymers with a polydispersity >1,2.
