REPORT 972 A On the cover. Electrospray MS. Understanding the mechanism of a technique allows researchers to plan experimental parameters that will lead to the desired result. Although the whys and why nots for many electrospray MS parameters are understood, exactly how gas-phase ions are produced from small, highly-charged droplets is not. Paul Kebarle and Liang Tang of the University of Alberta review the mechanisms currently favored that, even though not yet certain, provide information about the conditions that exist in electrospray MS
REPORT 987 A Acoustic wave microsensors. Although originally regarded as mass detectors, this versatile class of sensor can also measure other physical properties at the sensor's surface. In the second of a two-part series, Jay W. Grate of Pacific Northwest Laboratory, Stephen J. Martin of Sandia National Laboratories, and Richard M. White of the University of California-Berkeley discuss aspects such as viscoelastic thin-film properties and polymer transitions, polymer-coated vapor sensors, and sensor behavior in the liquid phase
