Накратко на български
Органичните съединения в атмосферните аэрозоли се анализират чрез нов автоматизиран метод за разделяне и разпознаване на химическите им компоненти. Това помага за определяне на източниците на частиците и подобрява моделите за промените в климата.

Цел на проекта
Aerosol particles are ubiquitous and influence our life directly by inhalation, or indirectly by contribution to climate changes. Knowledge of organic content of the aerosol particles is crucial for specification of their source, and for monitoring of their fate. This proposal suggests novel approach for complex determination of organic species in aerosol particles.The aerosol particles will be deposited by an impactor, a device for precise and selective aerosol collection. Extraction of the organic content from impactor membranes will be performed by supercritical fluid extraction (SFE) modified specifically for this purpose. It offers an automated and environment-friendly alternative to traditional liquid extraction methods. The extract will be analysed b y 2-dimensional liquid chromatography (2-D LCxLC) with mass spectrometry (MS). An on-line connection between SFE and 2-D LCxLC will be developed and employed for the analysis of aerosol samples.The comprehensive mode of 2-D LCxLC enables separation of complex mixture of components by employing two consequent columns with different stationary phases. Separation efficiency of such system abolishes the limits of conventional 1-column LC, and allows determination of wide range of components. This approach allows automated one-single-run determination of samples without the necessity of their manual pre-treatment. Further, no sample contamination or degradation affects the results in the closed on-line system.The results of our determination will be correlated with meteorology data, and utilised in development of atmospheric models. The whole research forms a part of the multi-disciplinary research project studying interactions among biosphere, aerosols, clouds and climate.
