Details of an analytical method re presented for the concentration, purification, and HPLC-MS-MS analysis for hydroxyatrazine (G-34048), hydroxysimazine (G-30414) and the three dealkylated hydroxy metabolites, GS-17794, GS-17792, and GS-17791. The water sample is acidified, analytes are adsorbed to a solid phase SCX column, and the analytes are eluted with a mixture of methanol, water, and ammonium hydroxide. The eluant from the solid phase extraction is removed and the extract reconstituted with methanol water. Quantitation of the extracts using HPLC-MS-MS with a minimum quantitation limit of 0.1 ng/L has given recoveries of 77 {plus_minus} 14%, 82 {plus_minus} 14%, 93 {plus_minus} 12%, 92 {plus_minus} 13%, and 93 {plus_minus} 11% for each of the five analytes for 165 fortified controls analyzed during the study.
