This standard specifies a general method for determining the average molecular mass and molecular mass distribution of polymers [ref. 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). Average masses and mass distributions are calculated from a mass calibration curve constructed using polymer and/or biopolymer standards. Therefore this method is classified as a relative method.
