Noise Characteristics of an Inductively Coupled Plasma-Mass Spectrometer

Abstract

Noise amplitude spectra for the signal from an inductively coupled plasma-mass spectrometer (ICP-MS) were measured and compared with those obtained with inductively coupled plasma-atomic emission spectrometry (ICP-AES). For the ICP-MS, white noise was dominant in background spectra. An audio-frequency noise peak at 200-350 Hz was observed and behaved much like the one noted earlier in ICP-AES. Unlike in ICP-AES, however, the frequency at which this noise peak occurs is dependent upon the sampling depth in the plasma. Keywords: Inductively coupled plasma; Noise spectra; Multielement analysis.
