author/source: Dionex
The United States Environmental Protection Agency (US EPA) provides guidelines for monitoring the presence of carbamate pesticides and related compounds in raw surface water using EPA Method 531.2. Detection of these regulated compounds at low levels is a challenge faced by many water testing laboratories using EPA method 531.2. The quicker, and more sensitive method described in the Dionex Application Update 177 indicates method detection limits are all ≤0.01 μg/L; and the quantification limit is 0.05 μg/L, which exceeds the requirement of EPA Method 531.2 (0.2 μg/L) and meets the restriction in 98/83/EC (0.1 μg/L). This application update and many others can be found at www.dionex.com under the Documents tab.
