【摘要】 采用傅里叶变换离子回旋共振质谱（FT-ICR MS）直接进样模式，对烟用香原料中的糖类成分进行快速定性分析，并应用高效液相色谱-蒸发光散射检测器（HPLC-ELSD）法同时测定三氯蔗糖、异麦芽糖、松三糖和蜜三糖等11种糖的含量。结果表明，所建方法既可在10 s内完成糖类化学成分的快速识别，又可同时测定多种糖类成分的含量，且线性关系良好、灵敏度高，方法重复性和精密度良好，各目标物的回收率为93.1%～103.0%。更多还原

【Abstract】 Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS) with direct injection mode was employed for rapid qualitative analysis of sugar components in tobacco flavors. Additionally, a high-performance liquid chromatography coupled with evaporative light scattering detector(HPLC-ELSD) method was developed for the simultaneous quantification of 11 sugars, including sucralose, isomaltose, melezitose, raffinose and others. Results demonstrated that the established method enabled rapid identification of sugars within 10 s and simultaneous quantification of multiple sugars with good linearities, high sensitivity, satisfactory repeatability and precision. Recoveries of target sugars ranged from 93.1% to 103.0%.更多还原
