摘要
The instrumentation of a new 40.68 MHz inductively coupled plasma (ICP) mass spectrometer is described. An optimization study has been carried out for the instrument. Of the many operating parameters, the carrier argon flow rate is the most sensitive and the optimum carrier argon flow rate is found to be much lower than the literature values for a 27.12 MHz ICP mass spectrometer. The analytical performance of the instrument, i.e., the detection limits, background mass spectrum and formation of oxides and doubly charged ions is also evaluated.
