GC-MS FOR THE CHROMATOGRAPHER
TRAINING COURSE
We have distilled critical knowledge of gas chromatography and mass spectrometry into a short, interactive course
Immediately enjoy the benefits in the laboratory by learning the absolute essentials of the technique through our unique multi-media examples and tutorial exercises.
This course is designed to highlight the powerful possibilities of GC analysis with mass spectral detection. We explain tuning and tune reports and instruct you how to use them as a powerful diagnostic tool.
We then discuss the functionality of the MS in detail including principles of quadrupole and ion trap mass filters. Ion detection devices will be explained, and the use of electron impact and chemical ionisation sources will be investigated with applicability to practical situations. GC parameters will also be considered with an explanation of the operation and troubleshooting of inlets and columns.
This course is for users of GC-MS equipment, or anyone interested in learning the analytical capabilities afforded by this type of instruments.
GC-MS FOR THE CHROMATOGRAPHER COURSE DETAILS
- How the different components of the mass spectrometer work with the gas chromatograph, from the transfer line to the vacuum pumps
- How ions are produced, filtered and detected, and the alternative ways different instruments achieve this
- How tuning affects the instrument and the data generated, and how to benefit from this knowledge
- The rich plethora of information that can be acquired and how to optimise instrument settings for high data quality
We offer flexible delivery options for this instructor-led course:
- On-site: one full-day session at your laboratory or any location of your choice.
-
Online: two half-day interactive sessions.
