Analytical Possibilities of Detecting Trace Quantities of Beryllium by ERIAD Mass-Spectrometry

摘要

The possibility of mass-spectrometric determination of the beryllium concentration in the air in work rooms is examined. Experiments have shown that the ERIAD ion source (electro-sprayng with controlled atomization in the source) gives the required rapid-analysis of the beryllium content, including at a level 10 times lower than the maximum admissible concentration. Evaluations show that such analysis takes no more than 30 min, including sample preparation; one mass-spectrometer can service 10-12 sampling points.
