Spectrographic Analysis of Air Samples for Beryllium Contamination

Volume 14, Number 2 (April 1960) Page 43-45

Brash, M.P.

A spectrographic technique for the determination of beryllium in atmospheric dust has been developed. Both a permanently installed low volume air sampler and a portable high volume sampler are employed for obtaining the air-borne dust samples. Solutions of the filtering media are used for spectrographic analyses, by a solution-spark technique using a rotating disk electrode. The method is sensitive to 0.05 micrograms of beryllium per cubic meter of air, with a coefficient of variation of less than 11% in the 0.5 to 2 microgram range.
