The development of the Rtx-CL Pesticides and Rtx-CL Pesticides2 columns demonstrates how computer modeling can be effectively employed in the design of stationary phases that yield optimum resolution for a specific list of compounds. In addition, these columns can be baked out the end of each analysis to remove high-boiling contaminants without degrading the stationary phase. They do not have the problems associated with cyanopropyl phases such as on-column methoxychlor and DDT breakdown and low maximum temperature. These application specific stationary phases will improve analyses that were previously difficult because of the reuse of general-purpose phases.
