Abstract |
An instrument developed for the routine measurement of aerosol mass using the beta-particle attenuation method is described and evaluated. Factors affecting the precision and accuracy of the measurement are discussed in detail. 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 used in modern dichotomous samplers. |
