A simple chiral analytical method was developed for the enantiomeric determination of cyflumetofen in cucumber, tomato, and apple by normal‐phase HPLC. The effects of mobile phase composition and column temperature on the enantioseparation were evaluated. Excellent separation was achieved at 25°C on a Chiralpak AD‐H column, with a mixture of n‐hexane and 2‐propanol (95:5, v/v) as mobile phase at a...
An effective chiral analytical method was developed for the resolution and determination of dinotefuran enantiomers in rice, tomato and apple samples. Dinotefuran enantiomers were baseline‐separated and determined on a novel chiral column, ChromegaChiral CCA, with n‐hexane–ethanol–methanol (85:5:10, v/v/v) as the mobile phase at a flow rate of 1.0 mL/min with UV detection at 270 nm. The resolution...
