Description

Jun Zhang and co-authors measure how readily a wood-smoke marker escapes from airborne particles. The marker, levoglucosan, is used worldwide to trace biomass burning in air samples. Yet how fast it evaporates in real air was poorly known, since its vapor pressure and mixing behavior were unmeasured.

Using a heated tube setup, the team found the pure compound's vapor level and showed it grows more volatile when mixed with other particle matter. Non-ideal mixing makes it flee the particle phase faster than simple models assume. Ignoring that effect would greatly understate its loss during transport.
