Scope

Main technical content: This standard specifies the liquid chromatography-tandem mass spectrometry method for the determination of herbicides in water. This standard is applicable to the determination of four herbicides, including Simazine, Atrazine, Acetochlor, and Butachlor, in drinking water and its source water. When the sampling volume is 1000mL, the minimum detectable mass concentration of this method for Simazine and Atrazine is 0.020μg/L; and for Acetochlor and Butachlor, it is 0.040μg/L.
