Beginning Gas Chromatography

January 30 to 31st 2019
New Brighten Community Center 

David Johnson and Richard Rossiter

The well-known MCF “Beginning Gas Chromatography” course is being updated and condensed into a new-style 2-day classroom format. This course is aimed at those who have recently started using gas chromatography and would like to understand more about how instruments function, learn how to maintain them, and see how GC methods may be developed and optimized. Others may also find this course informative, such as those who have responsibility for GC analyses even though they may not run the instruments themselves, those who are looking to expand their capabilities, or those who would like an opportunity to refresh their skills. Experience operating a gas chromatograph is not required to benefit from this course.

Instructors will be Dr David Johnson and Mr Richard Rossiter, who both have a wide experience of analytical problem-solving though their experiences in 3M’s Corporate Research Analytical Laboratory.

Outline –

GC separation – what goes on inside a column

The GC instrument – the functions of its parts, setting up a system

Column types – choosing a column from the array of stationary phases and dimensions available

Injection Techniques – liquid, headspace, thermal desorption

The GC Oven – programming for optimal separations

Detection – mainly flame ionization and quadrupole mass spectrometry

Peak Identification – how to know what you are looking at

Data handling and evaluation – turning raw data into useful results

System maintenance – keeping an instrument operating as it should

Troubleshooting – moving from problem recognition, through evaluation, to correction or escalation

Method development – where to start and how to optimize to meet different criteria

Future trends in GC – what might you put on your capital wish-list

Additional topics may be covered according to student interests.
