Humanity in Science: Combating Counterfeit with Capillary Electrophoresis

The Humanity in Science Award was created in 2015 to recognize outstanding developments in science that could change human lives for the better. There were many runners-up who did (and do!) amazing things for humanity. Recently, The Analytical Scientist sat down with each of them to catch up, and find out how their ventures have progressed in the last 12 months.

How Does Temperature Affect a Compound’s Retention Time?

The boiling point is the temperature where liquid has enough energy that molecules transferring into the vapor phase exert a pressure that is equal to the outside pressure. This allows molecules anywhere—not just the surface—to transfer to the gas phase.

Is Water Safe To Inject In Gas Chromatography?

In the first GC columns, gas chromatography phases were simply coated onto the column. This was mostly the case with packed columns, but also the same with the very first capillary columns. Injecting water onto these phases dissolved the phase and caused the phase to elute from the columns.
