摘 要：对家畜乳尤其是特种家畜乳脂肪甘油三酯（triacylglycerols，TAGs）进行系统鉴定和研究。采集荷斯坦牛、山羊、蒙古马和双峰驼原奶样品31 份，用超临界流体色谱-四极杆飞行时间质谱（supercritical fluid chromatography-quadruple time-of-flight mass spectrometry，SFC-Q-TOF-MS）检测鉴定TAGs组成，并进行主成分分析...
Methods: We analyzed 14 CHCl3 extracts of licorice roots (Glycyrrhiza glabra, G. uralensis, and G. inflata) using SFC-time-of-flight (TOF)/MS and LC-TOF/MS in conjunction with principal component analysis (PCA). The three species were assessed for discrimination based...
本技 术概述介绍了 Agilent 1260 Infinity 分析型 SFC 系统与 Agilent 6230 飞行时间 LC/MS (6230 TOF) 的联用.采用安捷伦喷射流 ESI 离子源.它能够兼容 SFC 系统,并使用超 热鞘气(氮气)使雾化器喷雾集中,从而获得更高的质谱灵敏度.优化了主要的离子源 参数,例如干燥气和鞘气的温度与流速以及雾化器压力和...
- 使用安捷伦全离子 MS/MS 技术通过 MS/MS 数据的选择性进行非靶向筛查。 -在 UHPLC 分离之外,支持毛细管电泳、SFC、2D-LC、甚至 GC-APCI 色谱接口。
SFC-APLI-TOF(MS) - a novel hyphenation to Atmospheric Pressure Laser Ionization Mass SpectrometryA commercially available SFC-analysis system was successfully hyphenated to atmospheric pressure laser ionization mass spectrometry. The coupling of high pressure SFC with ionization at atmospheric pressure was ...
乳真实性超临界流体色谱-四极杆飞行时间质谱质谱指纹主成分分析为探索家畜乳脂肪质谱指纹特征和建立真实性判别模型,采集蒙古马,荷斯坦牛,双峰驼,山羊,牦牛和水牛乳代表性样品56份,超临界流体色谱-四极杆-飞行时间质谱仪(Supercritical Fluid Chromatograph Quadrupole Time of Fight Mass Spectrometry,SFC-Q-TOF-MS)电喷雾...
Atmospheric-pressure laser ionization mass spectrometry (APLI-MS) is a powerful method for the analysis of polycyclic aromatic hydrocarbon (PAH) molecules, which are ionized in a selective and highly sensitive way via resonance-enhanced multiphoton ionization. APLI was presented in 2005 and has been ...
