摘要： 建立了阴离子表面活性剂α-烯烃磺酸盐(AOS)中多种组分(C14~18烯烃磺酸盐、C14~18羟烷基磺酸盐和少量二磺酸盐)的超高效液相色谱-四极杆飞行时间串联质谱(UPLC-Q-TOF-MS)分析方法。样品用超纯水超声溶解,过0.22 μm微孔滤膜,经Waters ACQUITY UPLC HSS C18色谱柱(150 mm×2.1 mm×1.7 μm)分离,采用电喷雾离子源(ESI)负离子模式对AOS进行四极杆飞行时间串联质谱分析,分析时间为16 min,各组分基本完全分离,可实现对AOS中多组分的定性定量分析。

Abstract: An analysis method for determination of various components in anionic surfactant alpha olefin sulfonate (AOS) product (C14~18 olefin sulfonates,C14~18 hydroxyalkyl sulfonates and few disulfonate) adopting ultra-high performance liquid chromatography-quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS) was established.The sample was dissolved in ultra purified water under assistance of ultrasonic irradiation and filtered with 0.22 μm micropore membrane.The filtrate was separated by Waters ACQUITY UPLC HSS C18 column (150 mm×2.1 mm×1.7 μm),and further analyzed by quadrupole time of flight mass spectrometry using electrospray ionization (ESI) negative ion mode.Analysis time is 16 min.The various components in the sample can be substantially completely separated.Via the analysis method,the content of the components with separate carbon chain length of the sample can be identified and examined.

Key words: anionic surfactant, alpha olefin sulfonate, analysis
