Abstract
A conventional high-voltage spark, operating at 50 Hz, is used for sampling and nebulising material from solid conducting samples. Gas, fed through the spark chamber, transports the metal particles into a flame or plasma for analysis by atomic-absorption, atomic-fluorescence or plasma emission spectrometry. Calibration graphs for the copper present in aluminium alloys and iron in brass are presented.
