Method of regulating the high-frequency electrical power delivered to a plasma torch in a spectroscopic analysis apparatus making it possible to produce a plasma flame with stable characteristics, characterised in that the high-frequency electrical power generator is slaved to the measurement of a light intensity emitted by this same plasma. According to requirements, this slaving is carried out on the basis of the total intensity of the plasma light, or of a discrete spectral line or of a line generated by a supporting gas or by a solvent or by a trace element. <IMAGE>
