On-line generated ozone as a reactive cell gas for tandem quadrupole inductively coupled plasma mass spectrometry†
Abstract
On-line generated ozone was introduced as the cell gas of tandem quadrupole inductively coupled plasma mass spectrometry. Product ions of the ozone reaction showed that the formation of singly charged monoxide ions and dioxide ions was apparently improved for most elements, resulting in maximum improvement of the signal intensity by over 1000 times.
