Abstract

Sample rotation during excitation in metal emission spectroscopy is quite common. Rotating sample holders are available commercially. The advantages of sample rotation during excitation are: 1) More representative sampling is achieved as more of the sample surface is exposed to electrical discharge; 2) Improved spectral intensity, because a larger area of sample is exposed during emission; and 3) Minimum matrix effect, because the rotating sample can avoid local heating. Results with techniques using rotating samples have been reported by Wang (<i>1</i>) and Wang, <i>et al.</i>, (<i>2</i>) who used briquetted soil samples, which had been fused and mixed with graphite, by Mitchell and Scott (<i>3</i>), who used plant-ash briquets, and also by Gillete <i>et al.</i>, (<i>4</i>) who analyzed cements and nickel ores.
