Abstract
The invention provides a spark generator for generating a spark for optical emission spectroscopy (OES), wherein the spark has a current waveform comprising a first modulated portion which comprises a plurality of relatively high current and high gradient peaks of variable amplitude and/or inter-peak duration and a second modulated portion of relatively low current and low gradient which is substantially without modulated peaks. The spark is preferably generated from two or more programmable current sources. The invention also provides an optical emission spectrometer comprising the spark generator and a method of optical emission spectroscopy using the spark generator.
