Major fraction of arctic and polar cloud condensation nuclei (CCN), upon which cloud droplets form, are of secondary origin, i.e., they are formed from gas phase via homogeneous nucleation and subsequent cluster growth by condensation of low volatile vapours. The low volatile vapours required in the process are formed in gas phase oxidation of both biogenic volatile compounds and anthropogenic …

Secondary Electrospray Ionization Mass Spectrometry for Medical Diagnosis of Respiratory Diseases

Ahlmannsalen, Geovetenskapens hus

Exhaled breath contains relevant information on a person’s health status. Our vision is to use real-time and completely non-invasivechemical analysis of exhaled breath for applications such as medical diagnosis, monitoring progress and treatment of diseases, drug compliance, pharmacokinetics, and others. The methodology we use to analyze breath in real time is based on secondary electrospray ionization coupled to high-resolution mass spectrometry (SESI-HRMS). It …
