AN ATMOSPHERIC-PRESSURE MICROPLASMA JET SOURCE FOR OPTICAL EMISSION SPECTROSCOPY OF LIQUID SAMPLE

摘要

An atmospheric-pressure microplasma jet source has been developed as a core device for the miniaturized ICP-OES (inductively coupled plasma - optical emission spectros-copy) system. This paper presents the production of high density plasma jets using a compact VHF transmitter for automobile and the optical detection of emitted spectra from tiny amounts of sample solution injected into the microplasma jet.
