Some aspects of secondary ion mass spectrometry of organic compounds

Abstract

After a short survey of the historical development of organic SIMS, the main experimental results of organic secondary ion formation are summarized in the frame of a precursor model. Results of static SIMS investigations of the (M+H)⁺ -, (M−H)⁻ -, and (M−H)⁺ - emission from metal supported amino acids and of different organic compounds in a glycerol matrix are reported. The performance of a new time-of-flight instrument for SIMS is demonstrated.
