Beta gauge instrumentation for the measurement of aerosol mass
Abstract
An instrument developed for the routine measurement of aerosol mass using the beta gauge particle attenuation method is described and evaluated. Factors affecting the precision and accuracy of the measurement are discussed. Results of intercomparison studies between the beta gauge method and conventional gravimetric are presented. The design of the present instrument is particularly well suited for the automatic analysis of membrane filters obtained from modern dichotomous samplers.
