Prof. Hewitt told us: "The Ionicon PTR-MS offers us the excellent sensitivity and time resolution that we need for making virtual disjunct eddy covariance flux measurements of biogenic VOCs from forests to the atmosphere. In addition, the excellent service offered by Ionicon allows us to explore innovative uses of the instrument. For example, with their help we are now planning to measure landscape scale fluxes by mounting the PTR-MS on a small airplane."
