HPLC Separation of 2-Naphthoxyacetic acid

 

2-Naphthoxyacetic acid was included in a EURL (European Union Reference Laboratory) report for using QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) single residue methods. Primesep 100 & Obelisc R were used to separate 2-Naphthoxyacetic acid. 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.
