On November 9 and 10 the American Society for Mass Spectrometry held its annual Fall Workshop in Washington, DC. The subject was the time-of-flight mass analyzer; and the workshop attracted more than 70 participants. The invited “instructors” focussed primarily on instrumentation, while seventeen contributed posters dealt with theory, instrumentation and applications. The range of topics included plasma desorption, high mass analysis, multiphoton processes, reflectrons and other energy focussing devices, data acquisition and the use of TOF analyzers in conjunction with chromatography.
