我们报告了一种质谱访问路线，通过高分辨率电喷雾电离质谱（HR ESI MS）分析非极性差电离合成聚合物，利用增压技术通过氯化物附着。新的质谱程序允许表征的聚烃，其中包括难以电离的聚合物，如聚（苯乙烯）（PS）（范围从1700至18 000克mol-1）和首次报道使用ESI作为电离方法聚（1，4-丁二烯）（PBD）（范围从1000至10 000克mol-1）。该方法也适用于其他合成聚合物，包括聚（2-乙烯基吡啶）（P2 VP）和聚（丙烯酰胺）（PAAm）。强有力的氯化物附着使得能够检测多电荷多烃（高达四重电荷）。使用增压剂（环丁砜，碳酸丙烯酯，和间硝基苄醇）的这些电荷状态的操纵进行了系统的评估。我们的调查包括对T...
We report a mass spectrometric access route to analyze nonpolar poorly ionizing synthetic polymers exploiting supercharging technology by chloride attachment via high-resolution electrospray ionization mass spectrometry (HR ESI MS). The novel mass spectrometric procedure allows for the characterization of polyhydrocarbons, which include hardly ionizable polymers such as poly(styrene) (PS) (ranging from 1700 to 18 000 g mol–1) and—for the first time reported using ESI as ionization method—poly(1,4-butadiene) (PBD) (ranging from 1000 to 10 000 g mol–1). The method is also applied to additional synthetic polymers including poly(2-vinylpyridine) (P2VP) and poly(acrylamide) (PAAm). The powerful chloride attachment enables the detection of multiply charged polyhydrocarbons (up to quadruply charged). A systematic assessment of the manipulation of these charge states using supercharging agents (sulfolane, propylene carbonate, and m-nitrobenzyl alcohol) is carried out. Our investigations include an assessment of t...
