Hollow Cathode and New Related Analytical Methods

Аннотация

History of the development of a hollow cathode as a version of a discharge cell for optical emission spectroscopy and glow-discharge mass spectrometry is discussed. Special attention was paid to the contribution of colleagues from the Department of Analytical Chemistry at the St. Petersburg State University to research, development, and implication of analytical systems with glow discharge, including discharge in a hollow cathode. New analytical methods developed on its basis and versions of their application are described, covering direct elemental and isotopic analysis, depth profiling, determination of hardly ionized elements in solid-phase samples of different conductivity, and the determination of volatile organic compounds in the air.
