With the advent of modern agriculture, and its vast selection of chemical pest control measures, the
farming community has made significant increases in productivity and efficiency. Crop yield per acre is
at an all time high, due in part to the role of pesticides and herbicides in mitigating the devastating effects
of many plant and insect pests.

However, the use of these chemicals can have drawbacks, including sur-
face and ground water contamination. EPA Methods, such as 508.1, are used to monitor pesticides and
herbicides in drinking and ground water. The optimized dual column method shown here satisfies all
method requirements in half the analysis time, significantly improving sample throughput.
