A modified Perkin-Elmer HGA 300 graphite furnace has been investigated for sample introduction into inductively coupled plasma mass spectrometry (ICP-MS). Its application for the reduction of matrix related isobaric interferences at m/z 56 (ArO + and

The mass spectral background features of a moderate-power nitrogen microwave-induced plasma are presented. In general, the mass spectral background obtained from a nitrogen plasma is less congested at low mass than is the case with argon ICP-MS. In a

The moderate-power nitrogen plasma is evaluated as an alternative ion source for plasma mass spectrometry. The nitrogen MIP-MS exhibits linear dynamic ranges of about 3–4 orders of magnitude and low ppb to sub-ppb detection limits for most elements

An He-Ar mixed gas inductively coupled plasma (ICP) was investigated for use as an ion source for plasma mass spectrometry (MS). The addition of He to Ar produces a plasma capable of ionising high ionisation potential elements more efficiently than t

The determination of phosphorus and sulphur at trace levels is not possible by conventional atmospheric pressure plasma mass spectrometry because of high background signals at m/z= 31 (14N16OH+) and m/z= 32 (16O2+). The reduced-pressure plasmas decre

A low-pressure helium microwave-induced plasma was interfaced to a mass spectrometer and the system was utilised as a detector for gas chromatography. The over-all system was optimised with respect to microwave power and the first-stage pressure of t
