HPLC Analysis of Herbicide 2,4-DB on Coresep 100 Mixed-Mode Column
Application description
2,4-DB or 4-(2,4-dichlorophenoxy)butyric acid is a selective systemic phenylbutyric herbicide used to control annual and perennial broadleaf weeds. 2,4-DB is acidic and hydrophobic in nature and can be analyzed on Coresep 100 core-shell mixed-mode column in reversed-phase anion-exclusion modes. Retention time is controlled by an amount of ACN, buffer concentration and buffer pH. The method is suitable for analysis of various herbicides with LC/MS compatible conditions.
