| Abstract: | The mass spectrum rule of the fatty alcohol polyoxyethylene ether(AEO) with different number ethoxy(EO) was discussed by electrospray ionization mass spectrometry(ESI-MS). The main peak of AEO is M＋Na]＋ peak, and the response value differ with number of EO. The ionization efficiency is low when the number of EO is high and low, and the ion strength is disproportionate to the concentration of sample, so the value of the number of EO detected should be revised as it is not consistent with actual number. The dimer ＋Na＋ peak of and trimer＋Na＋ peak will appear when the concentration of the sample injected or the intensity of the trap ion is high. |
