Direct observation of the chemical evolution of flame-generated soot was demonstrated for the first time using real-time aerosol mass spectrometry. The data presented unambiguously show the transformation of particle phase polycyclic aromatic hydroca

Matrix effects in real-time aerosol mass spectrometry (RTAMS) were investigated using Standard Reference Materials (SRMs) obtained from the National Institute of Standards and Technology (NIST). Suppression of major component ions by much less concen

We are developing a method for the real-time analysis of airborne microparticles based on laser-ablation mass spectroscopy. Airborne particles enter an ion trap mass spectrometer through a differentially pumped inlet, are detected by light scattered

A method for detection of uranium in airborne microparticles in real time has been developed. Positive identification of uranium is achieved by isolating UO(2+) ions and following their reaction with residual oxygen molecules to yield UO(2)(+).

An apparatus for real-time MS/MS analysis of individual airborne microparticles by laser ablation in an ion trap is described. The performance has been demonstrated by the detection of tributyl phosphate and bis(2-ethylhexyl) phosphate on silicon car
