Analysis of Glyphosate, Glufosinate, and AMPA in Tap and Surface Water Using Open-Architecture UPLC with 2D-LC Technology

This application note describes the targeted analysis of glyphosate, glufosinate, and AMPA in tap and surface water. The limit of quantification in this study was measured at 1.0 ppb. EPA regulations have an MRL in water set at 700 ppb; the 1.0 ppb quantification limit clearly meets these regulations. Since FMOC has UV absorbance properties, similar detection limits could be reached with a photodiode array detector (PDA), thus offering a cost effective solution.
