摘要
目的:本试验比较胶体金法与气相色谱法两种方法在百菌清检测中的应用,并以此为基础建立一个不同于以前的监管模式。方法:采用胶体金法和气相色谱法检测百菌清。结果:胶体金试纸检测为阴性的样品,经气相色谱检测结果为未检出,添加的阳性和Cutoff值样品经气相色谱检测结果与胶体金试纸相一致。结论:与气相色谱相比较,胶体金法检测百菌清具有操作简便、观察直观、快速、省时的特点,其特异性、敏感性较高,可作为蔬菜采摘前百菌清农药残留自我检测的手段应用。
Objective： To detect chlorothalonil by colloidal gold strip and gas chromatography,comparing two methods used in the chlorothalonil detection,and establish a new supervision patten.Methods：Comparison of detecting chlorothalonil samples with colloidal gold strip and gas chromatography was performed.Results：Negative sample detected by collidal gold paper was not detected by gas chromatography.The result of colloidal gold and gas chromatography detection of addition sample of positive and cut off sample was consistent.Conclusion：Compared with gas chromatography,the colloidal gold method is simpler,more direct,more time-saving and faster.Therefore,it can be used on-the-spot to detect in chlorothalonil.
