小编小编，来生意了！

哟，老板有什么吩咐？

上次90种农残客户反馈良好，但现在有提高了要求，要用质谱扩项了。

好事啊，质谱可以做的事情太多了。

扩项的我们不会。。。。。。。能不能支持支持？

我看看，753的标准，且听我细细道来。

本应用主要介绍了如何使用赛里安气质联用仪对百菌清以及菊酯类农药的测定。

实验部分

? 仪器

SCION8300GC-8700SQ气质联用仪

▼ 气相质谱参数

试剂及标准品

菊酯类农药混标

结果

? 示例图

菊酯类农药混标法分离度与灵敏度良好，详见图1。

▲ 图1 菊酯类农药混标色谱图

? 校正曲线

菊酯类农药混标在10-200μg/l范围内的校正曲线，线性关系良好，相关系数R²≥0.991，列举第一组部分数据见图2，表1。

▲ 图2 菊酯类农药混标校正曲线

▼ 表1 菊酯类农药混标结果

? 重现性

菊酯类农药混标法峰面积RSD%≤4.96%(n=6)，结果详见图3。

结论

赛里安SCION 8500GC-8700SQ的操作简便，应对对食品中菊酯类农药残留量不仅快速，而且准确度高，重现性良好，能够完全满足各种复杂的分析需求。
