摘要: 芬太尼类物质作为一类新型精神活性物质，具有种类繁多、更新换代迅速、结构极其相似等特点，对其同分异构体进行准确定性分析是当前毒品分析工作面临的难题。超高效合相色谱法是实现同分异构体高效分离的有力手段，基于此，本研究建立了超高效合相色谱-质谱技术快速分离和检测芬太尼类物质的分析方法，对分离过程中色谱柱、改性剂、柱温等条件进行了优化。在最优条件下，采用Waters ACQUITY UPC² BEH色谱柱，以超临界流体CO₂为主要流动相、含20 mmol/L甲酸铵的甲醇为改性剂，在柱温50℃下进行梯度洗脱，使用Xevo TQD三重四极杆质谱进行检测，6.5 min内即可实现13种芬太尼类物质的有效分离，所有同分异构体的分离度均大于1.5，并且色谱峰对称性良好。方法的检出限为0.01~0.05 ng/mL，保留时间的相对标准偏差均小于0.6%，9种常见毒品对13种目标物的测定没有干扰。与常规的超高效液相色谱-质谱检测方法相比，本方法在异构体分离方面具有显著优势，可满足当前公安禁毒部门对于芬太尼类物质准确定性分析的需要。

Abstract: As a new class of psychoactive substances, fentanyls have the characteristics of wide variety,rapid replacement and extremely similar structures. The accurate identification of their isomers is a major problem faced by drug analysts. Ultra performance convergence chromatography is a powerful tool to achieve efficient separation of isomers. Therefore, a new method was established for fast separation and detection of fentanyls by ultra performance convergence chromatography-mass spectrometry in this work. The separation conditions of the chromatographic column, modifiers and column temperature were optimized. The separation and detection was conducted on Waters ACQUITY UPC² BEH column with supercritical fluid CO₂ as primary mobile phase, methanol containing 20 mmol/L ammonium formate as the modifier, column temperature at 50℃ and a Xevo TQD triple quadrupole as mass spectrometer. A total of 13 kinds of fentanyls were completely separated within 6.5 min with an above 1.5-resolution to all the isomers. The chromatographic peaks were perfectly symmetric. Methodological statistics showed that, 9 kinds of common drugs did not interfere with the determination of 13 kinds of target substances;the detection limits were 0.01-0.05 ng/mL and the relative standard deviations of the retention time were less than 0.6%. Compared with the conventional ultra-high performance liquid chromatography-mass spectrometry detection method, this method had significant advantages in the separation of isomers,which fully met the anti-drug public security departments' needs for the accurate identification of fentanyls.
