                     Analysis of Residual Pesticide in Foods
                     When analyzing residual pesticides in foods, it is advantageous to use a high-sensitivity selective detector. In contrast, an
                     FID, which is suitable for general-purpose applications, is used to comprehensively measure many different pesticides.
                     Using an ECD/FPD detector con guration provides high-sensitivity analysis of phosphorus, sulfur and halogen while an FID
                     measures a wide variety of pesticides.
