Differences in the relative molar response observed for a series of closely related analytes in glycerol solution using secondary ion mass spectrometry are attributable largely to differences in surface activity. These differences can be minimized if

A detailed understanding of the physical processes which can occur at the glycerol surface is essential to understanding the secondary ion mass spectra obtained from glycerol solutions. Because of differences in surface activity, the relative contrib
