Application of an orthogonal method for optimizing an inductively coupled plasma mass spectrometer.
The orthogonal method can be used to predict the optimum instrumental conditions and to guide the optimizing operations. This simplifies the ICP-MS optimization. In general, the final optimum parameter combination used in an analysis can be obtained after fine adjustments of the preferred parameters derived from the orthogonal experiment. This method can also be used to study the relationship between the parameter settings and the signal intensity deflection to improve the analysis of elements of a limited mass range or of isotopes.
