Title

A remote aerosol sampler to be used with charged-particle X-ray fluorescence analysis

Abstract

A remote aerosol sampler, capable of up to 3 weeks continuous sampling has been developed. It consists of an Anderson 2000 Inc. mini-sampler or personnel monitor requiring an air flow of 1.4 e/min, a flow meter, a vacuum meter, a bleed valve, a dry gas volume meter, and a pump. The pump is a Brailsford Model TD-4X2, and operates on a 24 volt D.C. power supply. The sampler consists of four impaction stages with a 0.4 μ Nuclepore backup filter. Particulates are removed from the plates in an ultrasonic cleaner with hexane solvent. The suspended particulates are collected on a 0.4 μ Nuclepore filter. Elemental analysis of the aerosol is accomplished by the method of charged particle X-ray fluorescence. The results of two samples taken in Utah County, Utah, are tabulated. Elemental composition is reported as ppm of particulate, as a ratio relation to stage 1, and as a ratio relation to iron. High values are reported for iron and lead, with most of the lead being collected in the filter.
