为避免非禁用的同分异构体干扰禁用芳香胺2-甲氧基-5-甲基苯胺的测定,通过超高效液相色谱方法(UPLC)对2-甲氧基-5-甲基苯胺及其同分异构体进行了分离测定.该方法的加标回收率为72.51%~96.95%,精密度RSD为0.63%~3.40%.在S/N(信噪比)=3的条件下,检出限均为0.1 mg/kg.该方法简便快捷,定性可靠,定量准确,有效地解决了禁用偶氮染料检测中2-甲氧基-5-甲基苯胺的假阳性结果问题.

In order to avoid the interference of the non-banned isomers on the determination of 2-me?thoxy-5-methylaniline, an effective ultra-high performance liquid chromatography (UPLC) method was estab?lished. The standand recoveries of UPLC method changed from 72.51% to 96.95% while the relative standard deviation (RSD) of precision experiments varied from 0.63% to 3.40%. The detection limits were al 0.1 mg/kg under the condition of signal to noise (S/N) of 3. The result method was rapid, simple, reliable and accurate, and effectively solved the false positive problem in the analysis of 2-methoxy-5-methylaniline.
