Over the past decade, aerosol mass spectrometry has developed into a powerful method for characterizing individual particles in air. Recent advances in the design of inlets and mass spectrometers have extended the size range of particles that can be analyzed. In this tutorial, fundamental aspects of particle motion in sampling inlets are introduced. Basic experimental configurations for achieving a high analysis rate and the ability of laser ablation to provide chemical composition information are reviewed. An example of the use of this technology to study atmospheric phenomena is also presented. Significant opportunity exists for designing new experiments at the interface of aerosol mass spectrometry and conventional molecular mass spectrometry. Copyright © 2000 John Wiley & Sons, Ltd.
