| Description
| - Following our recent observation that Pseudomonas bacteria in vitro emit hydrogen cyanide, we have found it necessary to investigate the ion chemistry of this compound and to extend the kinetics database for selected ion flow tube mass spectrometry (SIFT-MS) to allow the accurate quantification of HCN in moist air samples, including exhaled breath. Because of the proximity of the proton affinities of HCN and H2O molecules, the presence of water vapour can significantly distort HCN analysis in the presence of water vapour and a more sophisticated analytical procedure has to be developed. Thus, the reactions of H3O+(H2O)0,1,2,3 ions with HCN molecules have been studied in the presence of varying concentrations of water vapour, reactions on which SIFT-MS analysis of HCN relies. The results of these experiments have allowed an analytical procedure to be developed which has extended the kinetics database of SIFT-MS, such that HCN can now be quantified in humid air and in exhaled breath.

- Vzhledem k nedávnému pozorování emise kyanovodíku bakteriemi kmene Pseudomonas %22in vitro%22 bylo třeba prozkoumat iontovou chemii HCN a rozšířit databázi kinetických dat pro metodu proudové trubice s vybranými ionty SIFT-MS tak aby bylo možno přesně stanovit koncentrace HCN ve vlhkých vzorcích vzduchu, včetně exhalovaného dechu Protože protonové afinity HCN a H2O jsou velice blízké, přítomnost molekul vody může narušit analýzu HCN za přítomnosti vodní páry a proto bylo nutno vyvinout sofistikovanou analytickou proceduru Reakce iontů typu H3O+(H2O)(0,1,2,3) s molekulami HCN byly prozkoumány v závislosti na proměnné koncentraci vodní páry. Databáze kinetických dat pro metodu SIFT-MS byla rozšířena a HCN nyní může být kvantifikováno ve vlhkém vzduchu a exhalovaném dechu. (cs)
