Chromatography connected with ion mobility spectrometry (IMS) is not commonly used, but is being investigated more. IMS is an independent analytical technique with very good detectability and a rather small separation ability. One favourable property of IMS is that it can work with ambient pressure and can be easily connected to a gas chromatograph. Analytical applications of GC–MS are very different and encompass investigations into food, medical science, environment, drugs of abuse, chemical warfare agents, and explosives.

How would you analyze a bag of gummy bears that showed up on your laboratory bench? This was the challenge taken on by teams of analysts in advance of the Conference on Small Molecule Science (CoSMoS) that was held in August 2015 in San Diego, California. This article shares insights from how the finalists approached the question.
