Aminotriazole is a polar and water-soluble organic pesticide and its preconcentration cannot be performed using either liquid-liquid extraction or solid-phase extraction with reversed-phase sorbents such as C,, silica, apolar copolymers or porous graphitic carbon. Aminotriazole can be ionised and it

## Abstract A novel chiral stationary phase (CSP) for HPLC was prepared by bonding (__R__)‐1‐phenyl‐2‐(4‐methylphenyl)ethylamine amide derivative of (__S__)‐valine to aminopropyl silica gel through a 2‐amino‐3,5‐dinitro‐1‐carboxamido‐benzene unit. The CSP was used for the separation of some amino a
