Scope

This document specifies the liquid chromatography method for determining aldicarb, carbofuran, and methomyl in water.
This document is applicable to the determination of aldicarb, carbofuran, and methomyl in surface water, groundwater, and drinking water using the liquid chromatography method.
When directly injecting a sample with a volume of 100 μL, the method detection limit for the target compounds is 0.150 μg/L to 0.180 μg/L, and the determination limit is 0.600 μg/L to 0.720 μg/L.
When the sample is subjected to solid-phase extraction and concentration, with a sampling volume of 100 mL, the method detection limit for the target compounds is 0.015 μg/L to 0.020 μg/L, and the determination limit is 0.060 μg/L to 0.080 μg/L.
The method detection limit and determination limit for the target compounds shall comply with Appendix A.
