McIntyre, N S

The application of secondary ion mass spectrometry (SIMS) to the study of organic polymeric surfaces has increased rapidly in recent years and has been extended to the organic constituents of coals. The detection of inorganic constituents in such organic matrices using SIMS is limited by the strong background contribution from molecular ions. A method for the suppression of molecular ions in SIMS spectra, known as specimen isolation (SI) has been introduced. The application of the SI-SIMS technique has now been extended to the analysis of some highly insulating organic polymer and coal surfaces. Examples of the results obtained are given.
