The gas-phase detection system we developed with my
colleagues was published in the Journal of Analytical
Chemistry in January 2014. By using the properties of
surface wetting the devices creates discrete micro-volumes
for chemical analysis without the need for expensive
microfabrication. This allows for continuous monitoring of
gaseous flows by taking away time-consuming sample
preconcentration steps.
