本文应用聚乙二醇400(PEG400)作内标,通过电喷雾-飞行时间质谱测定5个氨基醇类化合物及衍生物的准确质量,并考察了锥孔电压、锥孔温度等因素对准确质量测定的影响.%Amino alcohol derivatives were studied by Turboionspray - time - of- flight mass spectrometry (TIS - TOF - MS) with the aim of determining the accurate mass of their protonated molecule ions.Polyethylene Glycol (PEG) was used as the internal reference. Compared with the theoretical values, all relative errors were less than 5 × 10 -6. The effects of nozzle potential, nozzle temperature, acquisition rate, etc. on accurate mass determination were also studied.
