GC Method Development Video Training Course
Session 3

 
 
Column dimensions, temperature programming, introduction to GC detectors

In this session we investigate the important choices which govern the choice of GC column dimensions and how to optimize efficiency and analysis time. 

We also discuss sample screening methods to investigate the retention behaviour of the analytes and make some initial decisions regarding the requirements for the temperature program. 

Using temperature programming theory, we investigate how to optimize the gradient parameters such as initial and final temperature and the slope of the temperature gradient.  We discuss the use of mid-ramp holds for separating critical peak pairs within the analysis.  We also begin our discussion on GC detectors by examining the range of detector types available and the factors which govern detector selection.
