Abstract

The sizes and intensities of cluster ions formed by fast atom bombardment from a series of organic salts in nearly saturated solutions have been evaluated. Clusters involving as many as 29 anions and 30 cations have been recorded for ceslum perfluorohexanesulfonate. The average mass of this n equals 29 cluster is 15,561. 1. Abundances of the cluster ions are found to vary as a function of salt concentration in the liquid matrix and the number of ion pairs in the clusters. The abundance of the organic salt cluster Cs(CsC//6F//1//3SO//3)//1//9** plus at m/z 10,240. 4 was found to be 8 times greater than the abudance of the Cs//4//0I//3//9 cluster at m/z 10,265. 5.
