METHOD FOR MEASURING POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a method for simultaneously and more accurately measuring a composition distribution of multiple kinds of constitutional units constituting a polymer.

SOLUTION: A method for measuring a polymer includes; a mass spectrometry step for performing mass spectrometry by using a mass spectrometer on the condition that a peak half-value width is equal to or less than 0.1 Da; and a peak pick step for specifying corresponding peaks for each component which has the same compositions of terminal groups and also the same compositions of constitutional units except for the terminal groups in obtained mass spectra.
