I deal with chemical analyses to be carried out on samples with different matrices, with the aim of determining, through chemical and physical parameters, the composition both qualitative and/or quantitative of the samples. My training comes from my internships and studies but not least from my master’s thesis work, which dealt with the ” Comparison between methodologies for the analysis of atmospheric particulate matter,” at ARPA Sicilia, air quality section. In addition to dealing with the analysis of sediment samples and water filters, I manage the chemistry laboratory instrumentation as well as the inventory of reagents.
