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

What do I need in order to take the course?

1. A personal computer or tablet (Windows, Mac,iOS,or Android)
2. A high-speed (broadband) internet connection
3. A phone connection with headset or speakerphone

Here’s how it works:

1. After you register we’ll e-mail your course log-in information and password.
2. Download and print a hard copy of the course handout (approximately 200 pages).
3. About five minutes before the start of the course, log in to www.gotomeeting.com to download the gotomeeting client and check in for the course. Dial the phone number* for the conference call connection that you were given in your confirmation e-mail.
4. The course runs a total of six hours in three 2.5-hour sessions.

*Standard long-distance phone rates will apply (approximately $10.00).

What if I can’t make it?

All sessions are recorded and will be available for review for a month after the end of the course; if you miss a session, you can catch up at your convenience. If you must cancel, please call at least 48 hours prior to the start of the course in order to receive a refund. No refund will be made for cancellation within 48 hours of the course.
