【摘要】 建立了同时测定猪肉中四环素族、氯霉素和克伦特罗的固相萃取-高效
液相色谱(SPE-HPLC)测定方法,采用Oasis HLB固相萃取柱净化萃取,Diamonsil TM C18色谱柱分离,磷酸盐缓冲液(pH至2.5)-乙腈梯度洗脱,检测波长245 nm。结果表明:该测定方法对土霉素、四环素、金霉素、氯霉素和克伦特罗测定的线性范围均为2~12μg/ml,基底加标回收率为93.6%~96.1%,检出限符合国标要求,分离度和重现性良好,可用于肉类食品安全与质量监控,方法简便、可靠、实用、覆盖面广。 更多还原
【Abstract】 A method determining the race tetracyclines,chloromycetin and clenbuterol in pork was developed.The method was based on SPE(Oasis HLB column),separated by Diamonsil TM C18,and using a mobile phase of phosphate buffer solution-acetonitrile in gradient elution,detected with wavelength 245 nm.The results showed all the goal components presented linear relations in the scope of 2~12 μg/ml.The matrix recoveries ranged from 93.6 % to 96.1%.The detection limits complied with National Standards.The esta... 更多还原
