The Impact of pH and Ion-pair Chromatography

by | Liquid Chromatography

FHPLCAre you new to HPLC, or do you supervise new users of HPLC? 'Fundamentals of HPLC' is taught by Tom Jupille, a world-class expert in HPLC, and represents an opportunity to give new users a firm grounding in the fundamentals of HPLC economically and with minimum disruption to work schedules. “Fundamentals of HPLC” is intended for beginner chromatographers. No hands-on LC experience is required, but you should have a solid grasp of basic chemistry.

In the 'pH & Ion Pair' module in the 'It's all About Chemistry' section, we’ll look at the impact of pH on ionizable analytes in reversed-phase, and explore the use of a ion-pair chromatography (in effect, a variant of reversed-phase) for ionized compounds.

You will learn about:

  • Effect of pH on reversed-phase retention (k')
  • Effect of eluent pH on selectivity in reversed-phase HPLC
  • Common buffers for chromatography
  • Ion-pair reagents for HPLC
  • Best way to minimize artifacts in ion-pair chromatography
  • Effect of ion-pair reagents
  • Problems in ion-pair HPLC

This module has a complementary quiz. By correctly answering all of the quiz questions for all of the modules in the 'Fundamentals of HPLC' course you will be able to download your certificate of completion.

By taking this online course you will acquire a good understanding of the fundamentals of HPLC and get a better knowledge of the key concepts involved. The course is aimed at new users, as well as managers, supervisors, auditors, reviewers, etc. who use information generated by HPLC but do not necessarily do chromatography themselves.

The course price is US$ 189 for one user for 12 months of access. Multi-user pricing is also available, as are site licences for larger teams with multiple course requirements.
