Description

Live-On-The-Web: Making LC Methods Work

Who should take this course?

If you use HPLC or UHPLC methods and want a thorough grounding in what to do when problems arise, then , “Making LC Methods work” is the course for you. It’s designed for chemists and biochemists who use LC as a regular part of their jobs, but technicians with some LC experience will also find the course valuable. No previous formal LC training is assumed, but participants should have at least 6 months of “hands-on” experience with liquid chromatography.

What does it cover?

“Making LC Methods Work” focuses on reversed-phase chromatography, and assumes that you are starting with an existing, validated (or at least, “known to work”) method. We’ll cover things like:

  1. Major causes of failure to pass system suitability tests
  2. How to tell whether problems are due to chemistry or hardware
  3. A systematic strategy to identify problem causes efficiently
  4. How to maximize column life
  5. Special techniques such as gradient elution, quantitation, and sample pretreatment
  6. The most effective, timesaving, money saving approaches to preventing common method failures.

. . . And much, much more
