摘要：

Noise-amplitude spectra were measured for inductively coupled plasma (ICP) atomic emission spectrometry. These spectra indicate that a significant reduction of noise in the emission signal can be obtained by positioning a chimney over the ICP discharge. In this fashion, noise was reduced in the 200-500 Hz region of the frequency spectrum. The chimney had little effect on flicker (1/f) noise.
