The CHROMacademy Essential Guide Webcast: What GC-MS Operators Need to Know
Thursday 15th January 2015,
8:00am PDT / 11:00am EDT / 16:00 BST / 17:00 CEST
GC-MS is a powerful technique used in many laboratories worldwide to gain both qualitative and quantitative information. This webcast will improve your understanding of the theory and hardware used for GC-MS analysis whilst giving a clear insight into the variables which are key for successful analysis in a variety of application types. We will discuss special GC considerations, how analyte ionization works and the principles of mass analysis using quadrupole devices. We will show you how to interpret an MS tune report, the power of various MS operating modes and how to process and understand the data you generate.
Presented by Dr. John Langley (Southampton University) and Tony Taylor (Technical Director, Crawford Scientific).

What GC-MS Operators Need to Know - Tutorial Now Available
This module contains all you need to consider with regards to GC parameters when using GC-MS. The topics covered include carrier gases, injection and sampling modes, selection of column stationary phase and dimensions, and GC-MS fittings such as ferrules and septa. Each topic will give you the required knowledge and useful hints and tips to set up your GC analysis so that you get the best results which are compatible when coupling to an MS detector.
Ensuring the correct interface is used between the GC and MS instruments is paramount in GC-MS. This module will explain the working principles of GC-MS interfaces and how to select the correct interface for use with different types of GC columns and MS instruments. Common problems associated with the GC-MS interface are also discussed.
Understanding how an instrument works is great, but when do you have time to read a text book, or go to a course? Let CHROMacademy help. Dip in and out of concise modules and take 5 minutes to learn a little about the fundamentals of your analytical technique. Why not delve into GC-MS ionization techniques right now?
Leaks in GC-MS are particularly insidious. How do you know when you have a leak and where do you start to look for it.
It is something that will happen to all chromatographers at some point. Here is our quick guide to how to identify the source of GC-MS leaks.
This webcast will consider topics such as the anatomy of a typical EI source, the mechanisms of ionization, fragmentation and re-arrangement reactions and an introduction to EI mass spectral interpretation.
A must see for everyone using or developing methods for GC-MS.
The two main forms of ionization, Electron Ionization (EI) and Chemical Ionization (CI), will be discussed in depth. The molecular reactions which occur within the ion source to produce ions will be examined along with which form of ionization should be used for particular analytes. Finally, our speakers will impart some of their expert knowledge regarding optimization of the GC-MS process and some general interpretation strategies.
