the food safety problem. This paper presents for the first time, a multi-residues method for the simultaneous enantioselective determination of seven antipsychotics in pork, beef and lamb muscles. The behaviors of Chiralpak AGP toward changes in pH and organic modifier in mobile phase were studied, and all analytes were rapidly separated within 30 min. The calibration curves of all enantiomers were
在畜牧业中,非法使用抗精神病药已引起食品安全问题。本文首次提出了一种多残留的方法,可以同时对映选择性测定猪肉,牛肉和羔羊肌肉中的七种抗精神病药。研究了Chiralpak AGP对流动相中pH和有机改性剂变化的行为,并在30分钟内快速分离了所有分析物。所有对映异构体的校准曲线在1–250 ng g -1范围内均为线性,相关系数高于0.9931。目标化合物的回收率高于82.1%,重复性和中间精密度分别低于18.2%和17.4%。在三种基质中,检出限和定量限的范围为0.20至0.65 ng g -1和分别为0.40至1.00 ng g -1。所提出的方法可用于为手性抗精神病药的可靠风险评估提供更多信息。
