HPLC Analysis of Fungicide Tebuconazole on Coresep 100 Mixed-Mode Column

Application description

Tebuconazole is triazole fungicide used in agriculture to treat pathogenic fungi. Tebuconazole is hydrophobic and slightly basic. It retains on Coresep 100 column by combination of strong reversed-phase and weak cation-exchange mechanisms. This robust method is compatible with major detection techniques including mass spectrometry.
