Diclobutrazol Separation on Primesep and Obelisc HPLC Columns

Diclobutrazol is a fungicide based on 1,2,4-triazol. It is used in production of coffee and various cereal grains. Primesep 100 Obelisc R were used to separate diclobutrazol. Primesep 100 is a mixed-mode column which uses embedded ion-pairing groups and Obelisc can fine tune separations using both a long hydrophobic chain and ionic groups. Method is LC/MS compatible and can be used for many pesticides.
