Abstract

Abstract Investigations carried out to compare fast atom bombardment in positive and negative ion mode - combined with low or high resolution - with field desorption snowed that the former technique is more easily feasible. It proouces more fragment ions as compared with field desorption, which is a favourable aspect as regards structure elucidation, but a drawback in mixture analysis. Considering the difference in information obtained with the two techniques, it seems more practicable to use a combination than to apply only one of them.
