Real Time Measurement with Vocus PTR Mobile Laboratory

Ambient VOCs were measured with a Vocus S PTR-TOF during a 2400-km mobile laboratory project in Europe. 1,228 ion masses were monitored at 1-second frequency. This video highlights a selection of ion masses during a travel segment in Austria.

Three panels are shown. On the upper left, the drive path of the mobile laboratory on a map is shown. The track is sized and colored by the total VOC concentration. On the lower left, time-series concentrations of individual VOCs are shown. Gray shaded areas denote times when the vehicle traveled through a tunnel. The video in the upper right was recorded during this section of the drive and aligns with the plotted data.
