Summary

A novel form of ionic mobility spectrometer is described, based on the intrinsic properties of the construction of thePollak-Nolan nucleus counter. It is used for the size-frequency analysis of an artificial aerosol of Aitken nuclei at various stages in its decay. The first, construction of the instrument has been found to perform quite satisfactorily; suggestions for its improvement are discussed.

Zusammenfassung

Es wird ein neues Modell für ein Spektrometer zur Bestimmung der Ionenbeweglichkeit beschrieben, das auf den wesentlichen Konstruktionseigenschaften des Kernzählers vonPollak undNolan beruht. Es wird zur Analyse der Größenverteilung eines künstlichen Aerosols von Aitken-Kernen in verschiedenen Zerfallstadien benützt. Das Instrument hat sich in seiner ersten Ausführung als recht befriedigend erwiesen, und es werden Anregungen für seine Verbesserung diskutiert.

Résumé

L'auteur présente un nouveau modèle de spectromètre pour la mesure de la mobilité des ions. Cet appareil est basé sur les propriétés de conception du compteur de noyaux dePollak etNolan. Il s'emploie pour analyser la répartition des grandeurs d'un aérosole artificiel comprenant des noyaux de Aitken à différents stades de décomposition. L'instrument est tout à fait satisfaisant dans sa forme originale et l'on présente différentes suggestions pour l'améliorer encore.
