HILIC Method Development
Making HILIC work for you

Thursday 27th April 2017,
8:00am PST/ 11:00am EST/ 4:00pm BST/ 4:00pm CET

   
 

This webcast will provide you with the tools you require to understand and design HILIC methods.  

 Understanding the importance of stationary phase choice and how organic solvent, salt content, pH, and column temperature can effect separations will ensure method development is streamlined and the resulting methods produce robust results.

Presented by

Tony Taylor (Technical Director, Crawford Scientific)
Christophe Auberger (Technical Business Development Manager, Crawford Scientific)

Topics Covered

Practical hints and tips for developing and optimizing a HILIC separation

  • HILIC retention mechanisms
  • Mobile phase solvent choice
  • Effects of pH on HILIC separations
  • Effects of buffers and additives on retention and selectivity
  • Stationary phases

HILIC

This module introduces hydrophilic interaction chromatography (HILIC) as a novel mode of chromatography.  The separation mechanisms are illustrated using interactive animations. Chromatographic parameters (such as stationary phase chemistry, eluent composition, and the use of buffers and additives) which impact chromatography are detailed to allow methods to be developed.  Electrostatic repulsion hydrophilic interaction chromatography (ERLIC) is also discussed.

The Basics of HILIC

Hydrophilic interaction chromatography (HILIC) is applicable to the separation of very polar, highly water soluble analytes which are often poorly retained (if at all) under reversed phase HPLC conditions.  Although reversed phase HPLC stationary phases, such as those denoted ‘aqueous’, have been developed to work with highly aqueous mobile phases in order to promote retention of these very polar species, often they still do not work.

Mixed Mode Chromatography

This webcast considers the technique of mixed mode chromatography and its application areas. The mechanisms of mixed-mode chromatography are discussed alongside the parameters which can be used to optimize selectivity and retention. A series of useful illustrative examples are presented with strategies for column selection and screening to allow this technique to quickly become part of the analytical armory.
