用SNAP快速检测法与高效液相色谱法对牛奶样品中黄曲霉毒素M_1的检测,首先运用SNAP快速法对牛奶样品中的黄曲霉毒素M_1进行初筛,其中的阳性样品通过免疫亲和层析柱净化,并用带荧光检测器的高效液相色谱仪进行定性定量检测,从而比较SNAP快速法与高效液相色谱法之间的差异性及相关性.通过比较,SNAP快速法虽然简单、快捷,但检测结果有假阳性现象;液相色谱法前处理、分析过程较复杂,但灵敏度高,检测限低,回收率及线性关系好,结果准确可靠.

Aflatoxins M1 in milk was detected by SNAP rapid detecting and HPLC. SNAP rapid detecting was used to do preliminary screening of aflatoxins M_1, and then positive samples were purified by immuno-affinity chromatography and qualitative and quantitative measured by HPLC with fluorescence detector. Compared SNAP rapid detecting with HPLC method, the advantage of SNAP was more simpler and quicker, but the false positive rate was higher; the advantage of HPLC was more sensitive and reliable, and obtained better recovery rate and linear relationship, but the analysis process was more complex.
