The PTR-MS has been developed and used for a number of different applications. For example, Lindinger, Hansel and Jordan (1998) described the monitoring of metabolic processes in the human body by analyzing breath the monitoring of fruit and meat aging and the decay of vegetation. This monitoring is done by PTR-MS analysis of VOCs emitted, and the analysis of trace components of ambient air. Crutzen et al. (2000), Wameke et al. (2001), Williams et al. (2001), and Poschl et al. (2001) described measurements made by PTR-MS from an aircraft over the tropical rainforests of Surinam.

Figure 5. Isoprene and its oxidation products, methacrolein (MAC) plus methyl-vinyl ketone (MVK), have been measured by an airborne PTR-MS instrument. Data are from an aircraft flight (about 16 30 to 19 30 local time) over a tropical rainforest in Surinam, and show the vertical gradients of isoprene (detected at M69 ), and the sum of MAC and MVK (both detected at M71 ).

An investigation of VOCs over the tropical rainforest of Surinam by Crutzen and colleagues was the first time a PTR-MS instrument had been employed in flight [6-8]. This work was carried out as part of the Large-Scale Biosphere-Atmosphere experiment in...
