Cyflumetofen是由日本大冢化学公司开发的新型苯酰基乙腈类杀螨剂，与现有杀虫剂无交互抗性。2007年首次在日本获准登记并销售，用于果树、蔬菜、茶树等农作物和花卉防治寄生于植物的主要螨类。该产品为20%悬浮剂。对叶螨的卵和成螨均有效，对若螨的活性更高。根据试验对比，丁氟螨酯各方面效果均优于螺螨酯和阿维菌素。在土壤和水中迅速代谢、分解，是对环境友好的农药。

检测方法为日文，LCMS检测。

用什么方法检测？

看意思挺麻烦的，要用到加热回流装置，肯定是单独法了。

楼主怎么老跟日本打交道哈哈？

山东和福建是中国出口农产品的主要基地，主要出口对象是日本，也有韩国、美国、欧洲的。

Determination of cyflumetofen residue in water, soil, and fruits by modified quick, easy, cheap, effective, rugged, and safe method coupled to gas chromatography/tandem mass spectrometry.

A new, highly sensitive, and selective method was developed for the determination of the cyflumetofen residue in water, soil, and fruits by using gas chromatography quadruple mass spectrometry. The target compound was extracted using acetonitrile and then cleaned up using dispersive solid-phase extraction with primary and secondary amine and graphitized carbon black, and optionally by a freezing-out cleanup step. The matrix-matched standards gave satisfactory recoveries and relative standard deviation values in different matrices at three fortified levels (0.05, 0.5, and 1.0 mg kg(-1) ). The overall average recoveries for this method in water, soil, and all fruits matrix at three fortified levels ranged from 76.3 to 101.5% with relative standard deviations in the range of 1.2-11.8% (n = 5). The calculated limits of detection and quantification were typically below 0.005 and 0.015 μg kg(-1), which were much lower than the maximum residue levels established by Japanese Positive List. This study provides a theoretical basis for China to draw up maximum residue level and analytical method for cyflumetofen acaricide in different fruits.
