[Usefulness of Dilution for Rapid Simultaneous Determination of Residual Pesticides in Edamame (Immature Soybeans) by LC-MS/MS].

A rapid, easy and versatile, simultaneous analytical method by LC-MS/MS based on extraction of QuEChERS method (EN 15662:2008) was developed for the determination of residual pesticides in Edamame (immature soybeans). In this method, it allowed to prepare a test solution only dilution without purification using solid column. As a result, 202 analytes met the management criteria of the guideline for validity assessment (Ministry of Health, Labour and Welfare of Japan). Thus, the present method could be useful for a rapid simultaneous determination of residual pesticides in green soybean.
