Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) is shown to give inaccurate results for the analysis of low molecular weight ethoxylate polymers. It is demonstrated that when the degree of ethoxylation is low (n < 9), MALDI-TOFMS produces substantially high
