New breath related topics: sample collection for exhaled breath condensate and aerosol, development of real-time medical alerts, measurement of artificial atmospheres, and analysis of legalized cannabis product.

Exhaled breath technology is expanding beyond conventional gas-phase analysis, and conversely, methodology from other disciplines is finding applications in breath research. Recently, the authors attended conferences that incorporated new technologies into 'breath related' applications. The first was the International Submarine Air Monitoring and Air Purification (SAMAP) held in Uncasville Connecticut, November 2017, and the second was the Pittcon Conference and Exposition (Pittcon) held in Orlando, Florida, February 2018. Herein, we report some of the new topics and ideas encountered, ranging from very specific submarine related respiration issues revolving around carbon dioxide and oxygen from SAMAP to the eclectic topics of analytical chemistry from Pittcon.
