Air quality testing using electrochemical sensors and chromatographic techniques

This article presents equipment for taking samples of atmospheric air on sorption beds and then simultaneously analyzing parameters using low-cost electrochemical sensors. The device was made in a form of a module mounted to an unmanned aerial vehicle (drone), therefore it is possible to take samples from hard-to-reach locations. A laboratory chromatographic method is also described. It was used to analyze the chemical composition of the collected samples.
