Pesticide residue 239018 detection

Determination of Organophosphorus Pesticide Residues in Food - Method 1: Determination of Multiple Residues of Organophosphorus Pesticides in Fruits, Vegetables, and Cereals - Scope 1: This standard specifies the following: Dichlorvos, Dichlophos, Chlorphos, Bafenphos, Diazinophos, Ethylthion, Methyl Pyrimiphos, Methyl Parathion, Rice Blast Net, Water Thiophos, Oxquinophos, Daofengsan, Methyl Thiophos, Chlorphos, Ethylthion, Dimethoate, and Quinophos in Fruits, Vegetables, and Cereals Method for residual analysis of parathion and fenitrothion. This standard is applicable to the residue analysis of fruits, vegetables, grains, and other crops that have used twenty pesticide formulations such as dichlorvos. The sample containing organic phosphorus burns on a hydrogen rich flame, emitting characteristic light with a wavelength of 526 nm in the form of HPO fragments; This type of light flux filter is selected, received by a photomultiplier tube, converted into an electrical signal, amplified by a microcurrent amplifier, and recorded. Compare and quantify the peak area or peak height of the sample with that of the standard sample
