摘要
使用气相色谱质谱联用(GC-MS)和电喷雾四极杆飞行时间质谱(ESI-Q-TOF)对氢封端聚二甲基硅氧烷进行分析,通过谱图解析,确定了样品中有100个相对分子质量134～3 908的组分,分别属于4种同系物,包括2种链状聚二甲基硅氧烷和2种环状聚二甲基硅氧烷.
The polymethylsiloxane terminated with hydrogen was analyzed by Gas Chromatograph-Mass Spectrome- ter （GC-MS）and electrospray ionization quadrupole time-of-flight mass spectrometry （ESI-Q-TOF）. Through the interpretation of the mass spectrogram, the 4 series of homologues contained 2 types of catenarian polydimethylsi- loxane oligomer and 2 types of ringed polydimethylsiloxane oligomer were identified. And the 4 series of homologues contained 100 components from molecular weight 134 to 3908.
