A picture of polar iodinated disinfection byproducts in drinking water by (UPLC/)ESI-tqMS 来自 ACS 喜欢 0 阅读量: 174 作者:G Ding,X Zhang 摘要: Iodinated disinfection byproducts (DBPs) are generally more toxic than their chlorinated and brominated analogues. Up to date, only a few iodinated...
2.1.2 UPLC-TQMS的质谱条件 采用电喷雾离子源、正离子模式;毛细管电压为2.0 k V,锥孔电压为40 V;离子源温度为120℃,脱溶剂气温度为300℃;脱溶剂气流速为800 L/h,锥孔气流流速为150 L/h;扫描模式为MRM.FQs结构中含有羧基和氨基,当溶液为酸性时,其呈现阳离子状态,并在ESI+模式下,易形成[M+H]+准分子离...
采用 UPLC-Q-TOF/MS 定性分析黄芩酒炙前 后化学成分,利用 UPLC-TQMS 对 2 种饮片中 11 种黄酮类成分(黄芩苷,黄芩素,汉黄芩苷,汉黄芩素,千层纸素 A,千 层纸苷,野黄芩苷,芹菜素,高车前素,木犀草苷,白杨素)进行定量分析,并以含量为变量进行多元统计分析.结果 建 立了黄芩片,酒黄芩的特征图谱,标定 9 ...
Plasma samples from SD rats collected after the oral administration of 5 mg/kg triclosan were analyzed by ultra performance liquid chromatography (UPLC)-triple quadrupole mass spectrometry (TQMS) to support the pharmacokinetic study of triclosan. The method development was conducted with selected-ion-...
