1. Instrumental and methodological developments for isotope dilution analysis of gaseous mercury species
Abstract : This thesis deals with instrumental and methodological developments for speciation analysis of gaseous mercury (Hg(g)), based on isotope dilution analysis (IDA). The studied species include Hg0, (CH3)2Hg, CH3HgX and HgX2 (where X symbolises a negatively charged counter ion in the form of a halide or hydroxyl ion). READ MORE

4. Gas-sensors for Automobile Interiors
Abstract : The concentration of pollutants in the car compartment air is influenced not only by neighboring vehicles, but also by pollutants originating from the car's interior trim materials. These pollutants may cause nuisance and even pose a safety risk as some condense on the windscreen and form an oily film that dims the screen. READ MORE
