HAZEL (analyzer for the determination of HAZardous atmosphEric poLlutants). Start date: July 27, 2017. Duration: 24 months

HAZEL aims at the development of new instrumentation for the analysis of POPs (Persistent organic pollutants) in atmospheric samples, a series of compounds posing a high toxicity for humans and living organisms. Specifically, the project will focus on the detection of PAHs (Polycyclic aromatic hydrocarbons) and PCDD/F (dioxins and furans), which are the most hazardous pollutants among the POPs family. The new Analyzer will use a novel field-free photoionization source based upon Atmospheric Pressure Photoionization (field-free APPI) and an improved Differential Mobility Analyzer (DMA). The APPI source will efficiently ionize these non-polar analytes, whose ionization is complicated through the conventional ionization techniques. The improved DMA will effectively separate in mobility and deliver ions to the triple quad mass spectrometer, which will perform the final ion classification according to their mass to charge ratio (m/z) and fragmentation pattern. The novel analyzer will substantially reduce the sampling and analysis time, allowing the accomplishment of a series of new, thorough environmental studies and analyses at a significantly reduced cost per sample.
