Real-time detection of individual airborne bacteria

Airborne bacteria and bacterial spores were directly sampled by an ion trap mass spectrometer with an atmospheric pressure inlet system. Samples were aerosolized from suspensions of single species. The organisms were individually characterized in real time by laser ablation mass spectrometry. Either...

Description
Summary:Airborne bacteria and bacterial spores were directly sampled by an ion trap mass spectrometer with an atmospheric pressure inlet system. Samples were aerosolized from suspensions of single species. The organisms were individually characterized in real time by laser ablation mass spectrometry. Either positive or negative ions could be studied. Ions of a particular value of m/ z (mass to charge ratio) could be further characterized by tandem mass spectrometry in the ion trap.
