For secondary ion mass spectrometry of highly electronegative elements, the MCs2+ method provides greater sensitivity but may sometimes afford a different depth profile than the conventional MCs+ method for the same sample. Here, we report the difference system not only from the electronegativity of the elements but also from the electronegativity of the matrix. Copyright © 2012 John Wiley & Sons, Ltd.
