一种烟草及烟草制品中马来酰肼残留量的检测方法
摘要：
本发明公开一种烟草及烟草制品中马来酰肼截留量的检测方法，所述烟草及烟草制品包括烟叶和卷烟烟丝，包括以下步骤：配制标准溶液、盐酸回流提取、分散固相萃取纯化、UPLC‑MS/MS分析测定。本发明针对烟草抑芽剂马来酰肼，利用超高效液相色谱‑串联质谱仪（UPLC–MS/MS），建立UPLC–MS/MS快速分析烟草及烟草制品中马来酰肼残留量的方法。选取的串联质谱，分离度和灵敏度都明显高于标准方法（YC/T 405.5‑2011）的紫外检测器。
摘要（英）：

The invention discloses a method for detecting maleic hydrazide in tobacco and tobacco products that include tobacco leaves and tobacco shreds. The method comprises the steps of preparing a standard solution, reflow-extracting with hydrochloric acid, carrying out disperse solid extraction and purification, and carrying put UPLC-MS/MS analytical determination. For the tobacco bud inhibitor maleic hydrazide, ultrahigh-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) is used to establish the method for quickly analyzing maleic hydrazide residue in tobacco and tobacco products by UPLC-MS/MS. The tandem mass spectrometry selected herein is significantly higher than ultraviolet detectors of the standard method (YC/T 405.5-2011) in both separation degree and sensitivity.
