Trace Glyphosate Analysis in Drinking Water by LC-Fluorescence Post-Column Derivatization, EPA Method 547 (TN-1231)
Due to the chemical nature of glyphosate, the separation method required to chromatograph glyphosate is ion exchange or ion-exclusion which introduce a different set of challenges. The Rezex™ RFQ Fast Acid ion-exclusion column, allows this analysis to be done in about 15 minutes without the need for column regeneration after each injection. . Additionally, the RFQ Fast Acid column dimensions that was chosen reduces band broadening, which substantially improves the sensitivity of the method.
