ABSTRACT:
A magnetron glow discharge plasma device is utilized as a furnace for vaporization, atomization and excitation of analytical solution samples of trace elements for atomic emission spectroscopy. The apparatus includes a sample deposited on the glow discharge lamp, a spectrometer optically coupled to the lamp through a transparent wall portion of the furnace, a photoelectric detector connected to the spectrometer for sensing the light and converting the light to an electrical signal and a computer for digitally storing and processing the sent signal.
