Analysis of Air Samples for Beryllium by the Rotating Platform Spectrographic Technique

Abstract
Beryllium is determined spectrographically on air sample filter papers by direct sparking of the filter paper mounted on a silver disk which revolves on a rotating platform electrode apparatus eccentric from a silver counter electrode. The procedure is fast and precise, with a minimum of sample handling and can be used with samples containing as little as one mμg of beryllium
