液相色谱-串联质谱结合谱库检索测定猪组织中的9种β-兴奋剂残留量OA北大核心CSCDCSTPCD
Determination of nine β-agonist residues in pig tissues by liquid chromatography-tandem mass spectrometry combining with library search
建立了猪组织中9种β-兴奋剂(克伦特罗、莱克多巴胺、沙丁胺醇、利托君、特布他林、班布特罗、妥布特罗、西马特罗和异舒普林)多残留的液相色谱-四极杆/线性离子阱串联质谱(QTrap LC-MS/MS)检测方法.样品经β-葡萄糖醛苷酶/芳基硫酸酯酶酶解提取,液液萃取净化,以乙腈-甲酸水溶液为流动相,经C18柱分离后用QTrap LC-MS/MS进行多反应监测(MRM)、信息相关采集(IDA)、增强子离子扫描(EPI)和谱库检索分析.9种β-兴奋剂的线性…查看全部>>
A new method has been developed using a hybrid triple-quadrupole linear ion trap (QTrap) mass spectrometer for the fast detection and identification of nine β-agonists, clen-buterol, salbutamol, ractopamine, ritodrine, terbutaline, isoxsuprine, tulobuterol, cimaterol and bambuterol, in one single liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. The homogenized tissue samples were purified with liquid-liquid extraction after enzymatic hydro…查看全部>>
