Semi-automatic sample preparation device for analyzing beryllium traces in the air of a working room using ERIAD mass spectrometry (electrospray)

The article is devoted to the description of the developed device for semi-automatic sample preparation for analyzing traces of beryllium in the air of the working room using ERIAD mass spectrometry (electrospray). The principle of its operation is based on the adsorption of dust containing beryllium by charged droplets of solvent formed during pneumatic atomization in an electric field, and the subsequent collection of a sample from an irrigated filter, its dilution with a protonating solution and analysis in a mass spectrometer. The device allows to conduct rapid analysis with a sample preparation within less than 20 minutes. During the process of sample preparation manual operations are minimized with the exception of the final dilution of the sample for electrospray.
