Separation of Quaternary Ammonium Compounds Using a Bonded Polymeric Zwitterionic Stationary Phase

Patrik Appelblad;Merck SeQuant AB
June 1st 2011

Using a bonded polymeric zwitterionic stationary phase, in HILIC mode, polar quaternary herbicides like Diquat can easily be retained, with good peak symmetry. The impact of ionic strength and organic content in the mobile phase is discussed.
