A portable high-frequency pulse generator with a high-voltage output and ability to adjust the pulse output parameters over a wide range was manufactured. This generator was used to ignite an atmospheric high-frequency liquid-electrode discharge (RF-APLD), which burned stably for minutes between a metal rod and surface of an aqueous electrolyte solution. The RF-APLD spectrum was recorded. It was shown that, when an organic additive (polyethylene glycol) was added to the aqueous solution, lines from metals whose salts were present in the liquid appeared in the spectrum. Keywords: high-frequency generator, atmospheric high-frequency discharge with a liquid electrode (RF-APLD), atomic emission spectroscopy (AES), electrolyte spraying, solution analysis, polyethylene glycol.
