LC-MS Demystified

$947.00

This course is designed to provide basic knowledge and practical applications of LC-MS for liquid chromatographers. Most of the examples emphasize the most popular use of LC-MS/MS today: the analysis of drugs in metabolites and biological extracts. Although no previous experience with HPLC is necessary, the course will be especially valuable to those with some chromatography experience.

Live-On-The-Web: LC-MS Demystified

Who should take this course?

This course is designed to provide basic knowledge and practical applications of LC-MS for liquid chromatographers. Most of the examples emphasize the most popular use of LC-MS/MS today: the analysis of drugs in metabolites and biological extracts. Although no previous experience with HPLC is necessary, the course will be especially valuable to those with some chromatography experience.

What does it cover?

LC-MS Demystified is a course explaining the principles of mass spectrometric detection, the design and operation of mass spectrometers, and the interfacing of the MS to the liquid chromatograph to obtain both qualitative and quantitative data. This course covers:

  • MS operation, including the operation of the most popular LC-MS interfaces
  • How a quadrupole mass filter works
  • MS calibration and optimization
  • Ion production, fragmentation and detection
  • Operation in MS, MS-MS, and MS-MS-MS modes
  • Introduction to structure determination by product ion analysis

. . . and much more!

What do I need in order to take the course?

  • A personal computer (Windows, Mac, iOS, or Android)
  • A high-speed (broadband) internet connection
  • 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.
