Report on performance of inidvidual sensor system components in the PurPest project

This deliverable is a report on the performance of the individual components that will make upthe Sensor System Prototype (SSP). The report is a combination of tests done at the partners andat the intercomparison campaign at AIRMOTEC in April 2024. Performance is defined by thecomponents’ ability to detect and identify different VOCs from D1.6 “List of VOCs released fromrelevant pest described in the literature”. These VOCs include ethanol, 2-methyl-1-butanol, dlimonene and (E)-2-hexenal.In total, two gas chromatography systems, AIRMO (microVOC) and VOL (Scout3), anddifferent sensor technologies, SINTEF (SERS), Saftra (SERS) and UWAR (SMR), as well as,compound separation technology from UWAR (µ-GC) were tested. The two systems from AIRMO(microVOC) and VOL (Scout3) showed full or partial ability to detect the VOCs of interest. Thecomponents from SINTEF (SERS), Saftra (SERS) and UWAR (µ-GC and e-nose) need furtherdevelopment to be able to detect the target VOCs.
