The relative effects of adjustable fast atom bombardment (FAB) parameters (choice of matrix, primary atom flux, and primary atom energy) on the appearance of FAB spectra (including signal-to-noise, signal-to-background, and signal-to-matrix ratios) of several organic dyes have been investigated.

โฆ Synopsis
In the article by J. D. Reynolds and K. D. Cook in the March/April issue of the journal, there is an error in the second column of page 154. The last paragraph also approach this limiting value, they must do so at should read as follows.

Below this value, The two lowest curves of Figure 8 approach a liiit-sensitivity should suffer as S/N eventually becomes ing minimum value of E, (near 5). If the other curves limiting.

When mass-analysed ion kinetic energy (MIKE) spectra are required to discriminate between isomeric ions formed under conditons of fast atom bombardment (FAB) in the ion source, severe interference may be observed. The interfering peaks in MIKE spectra obtained with a reversed-geometry instrument can
