What GC-MS Operators Need to Know

This month’s webcast focused on the practical aspects of GC-MS.  This included GC considerations, such as, column dimensions and column stationary phase type and the impact these parameters can have on the physical operation of the instrument and the results obtained. We also discussed the theory of GC-MS in relation to ionization, types of MS experiment, and how to analyze data.  This webcast is essential viewing for al GC-MS users.

Our Quick guides, CHROMacademy course content, and archived webcasts and tutorials will provide you with further knowledge on how to implement, optimize, and troubleshoot GC-MS applications.

GC-MS Contamination

Contamination is an insidious problem in GC-MS.  This quick guide will help you to identify and avoid common sources of GC-MS contamination, which in turn will provide you with more reliable results, less system maintenance, and fewer instances of troubleshooting.

Improving Sensitivity of Environmental GC-MS Analysis

As with many sectors, detection limits for analytes in environmental samples are becoming ever lower. This challenges every step of the analytical process from sampling, to sample preparation, and the use and implementation of instrumentation which can provide the best sensitivity. Every step must be optimized to meet these sensitivity criteria, and, in this article, we will look at some areas of the GC-MS method which can be optimized to provide the optimum sensitivity.

Do You Know What’s in Your Beer?

Citrus, grapefruit, toffee, spice, apple, pear, biscuit, caramel… the list of flavors and aromas associated with beer is vast but how are they produced during the brewing process?  The hop variety used in the brewing process is responsible for the bitterness, aroma, and flavor characteristics.  These compounds can be extracted from hops by steam distillation, liquid-liquid extraction and analyzed using GC-MS.

GC-MS Ionization Processes

The focus of this Essential Guide webcast is GC-MS ionization processes.  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.  We will also impart some of our expert knowledge regarding optimization of the GC-MS process and some general interpretation strategies.
