With Tadeusz Górecki, Professor, University of Waterloo, Canada.
What's the latest from your lab?
We are continuing our efforts to develop a practical system for temperature programming of the second-dimension column in GC×GC, which can increase the 2D peak capacity by as much as 50 percent. We have developed a universal system in which a single metal 2D column serves three roles, as separation column, heater, and temperature sensor.
What are the key trends in GC×GC?
After a long period of relative stagnation, several new modulators have been introduced recently. While none of them are truly ground-breaking, they provide the users with more options. Plus, there are numerous interesting applications of GC×GC, as well as further advances in data handling and processing.
What challenges face your field?
The perceived complexity of the technique makes many users shy away from it, not helped by the difficulties with handling and processing huge data files. While GC×GC can produce a lot of data in a short time, extracting useful information from these data is not easy. On top of that, many users spend very little time on optimizing the separation itself. This can only be overcome by education on the one hand, and advanced “big data” techniques (involving artificial intelligence) on the other.
Predictions and aspirations?
It is more a dream than a prediction, but within my lifetime I would like to see GC×GC used for the most challenging samples in every gas chromatographic laboratory. As for my research, the goal has always been to provide the users with better tools to perform GC×GC separations, and I plan to carry on doing this until I retire.
